John Evelyn's Diary. 21st August 1655. I went to Ryegate [Map], to visit Mrs. Cary, at my Lady Peterborough's (age 33), in an ancient monastery well in repair, but the park much defaced; the house is nobly furnished. The chimney-piece in the great chamber, carved in wood, was of Henry VIII., and was taken from a house of his in Bletchingley. At Ryegate, was now the Archbishop of Armagh, the learned James Usher (age 74), whom I went to visit. He received me exceeding kindly. In discourse with him, he told me how great the loss of time was to study much the Eastern languages; that, excepting Hebrew, there was little fruit to be gathered of exceeding labor; that, besides some mathematical books, the Arabic itself had little considerable; that the best text was the Hebrew Bible; that the Septuagint was finished in seventy days, but full of errors, about which he was then writing; that St. Hierome's was to be valued next the Hebrew; also that the seventy translated the Pentateuch only, the rest was finished by others; that the Italians at present understood but little Greek, and Kircher was a mountebank; that Mr. Selden's best book was his "Titles of Honor"; that the church would be destroyed by sectaries, who would in all likelihood bring in Popery. In conclusion he recommended to me the study of philology, above all human studies; and so, with his blessing, I took my leave of this excellent person, and returned to Wotton, Surrey [Map].

In November 1657 [her father] Barnabas O'Brien 6th Earl Thomond died. His son [her brother] Henry (age 37) succeeded 7th Earl Thomond.

The Chronicle of Geoffrey le Baker of Swinbroke. Baker was a secular clerk from Swinbroke, now Swinbrook, an Oxfordshire village two miles east of Burford. His Chronicle describes the events of the period 1303-1356: Gaveston, Bannockburn, Boroughbridge, the murder of King Edward II, the Scottish Wars, Sluys, Crécy, the Black Death, Winchelsea and Poitiers. To quote Herbert Bruce 'it possesses a vigorous and characteristic style, and its value for particular events between 1303 and 1356 has been recognised by its editor and by subsequent writers'. The book provides remarkable detail about the events it describes. Baker's text has been augmented with hundreds of notes, including extracts from other contemporary chronicles, such as the Annales Londonienses, Annales Paulini, Murimuth, Lanercost, Avesbury, Guisborough and Froissart to enrich the reader's understanding. The translation takes as its source the 'Chronicon Galfridi le Baker de Swynebroke' published in 1889, edited by Edward Maunde Thompson. Available at Amazon in eBook and Paperback.

Samuel Pepys' Diary. 10th August 1663. Thence by coach with my Lords [her husband] Peterborough (age 41) and Sandwich to my Lord Peterborough's house; and there, after an hour's looking over some fine books of the Italian buildings, with fine cuts; and also my Lord Peterborough's bowes and arrows, of which he is a great lover, we sat down to dinner, my Lady (age 41) coming down to dinner also, and there being Mr. Williamson (age 30), that belongs to Sir H. Bennet (age 45), whom I find a pretty understanding and accomplished man, but a little conceited.

Samuel Pepys' Diary. 5th November 1666. Thence by coach to my Lady Peterborough (age 44), and there spoke with my Lady, who had sent to speak with me. She makes mighty moan of the badness of the times, and her family as to money. [her husband] My Lord's (age 44) passionateness for want thereof, and his want of coming in of rents, and no wages from the Duke of York (age 33). No money to be had there for wages nor disbursements, and therefore prays my assistance about his pension. I was moved with her story, which she largely and handsomely told me, and promised I would try what I could do in a few days, and so took leave, being willing to keep her Lord fair with me, both for his respect to my Lord Sandwich (age 41) and for my owne sake hereafter, when I come to pass my accounts.

Samuel Pepys' Diary. 23rd September 1667. Thence to the Excise office, and so to the Exchange [Map], and did a little business, and so home and took up my wife, and so carried her to the other end, where I 'light at my Lord Ashly's (age 46), by invitation, to dine there, which I did, and Sir H. Cholmly (age 35), Creed, and Yeabsly, upon occasion of the business of Yeabsly, who, God knows, do bribe him very well for it; and it is pretty to see how this great man do condescend to these things, and do all he can in his examining of his business to favour him, and yet with great cunning not to be discovered but by me that am privy to it. At table it is worth remembering that my Lord tells us that the House of Lords is the last appeal that a man can make, upon a poynt of interpretation of the law, and that therein they are above the judges; and that he did assert this in the Lords' House upon the late occasion of the quarrel between my Lord Bristoll (age 54) and the Chancellor (age 58), when the former did accuse the latter of treason, and the judges did bring it in not to be treason: my Lord Ashly did declare that the judgment of the judges was nothing in the presence of their Lordships, but only as far as they were the properest men to bring precedents; but not to interpret the law to their Lordships, but only the inducements of their persuasions: and this the Lords did concur in. Another pretty thing was my Lady Ashly's speaking of the bad qualities of glass-coaches; among others, the flying open of the doors upon any great shake: but another was, that my Lady Peterborough (age 45) being in her glass-coach, with the glass up, and seeing a lady pass by in a coach whom she would salute, the glass was so clear, that she thought it had been open, and so ran her head through the glass, and cut all her forehead! After dinner, before we fell to the examination of Yeabsly's business, we were put into my Lord's room before he could come to us, and there had opportunity to look over his state of his accounts of the prizes; and there saw how bountiful the King (age 37) hath been to several people and hardly any man almost, Commander of the Navy of any note, but hath had some reward or other out of it; and many sums to the Privy-purse, but not so many, I see, as I thought there had been: but we could not look quite through it. But several Bedchamber-men and people about the Court had good sums; and, among others, Sir John Minnes (age 68) and Lord Bruncker (age 47) have £200 a-piece for looking to the East India prizes, while I did their work for them.

Samuel Pepys' Diary. 3rd October 1667. He gone, I thence to my Lady Peterborough (age 45), who sent for me; and with her an hour talking about her husband's pension, and how she hath got an order for its being paid again; though, I believe, for all that order, it will hardly be; but of that I said nothing; but her design is to get it paid again: and how to raise money upon it, to clear it from the engagement which lies upon it to some citizens, who lent her husband money, without her knowledge, upon it, to vast loss. She intends to force them to take their money again, and release her [her husband] husband (age 45) of those hard terms. The woman is a very wise woman, and is very plain in telling me how her plate and jewels are at pawne for money, and how they are forced to live beyond their estate, and do get nothing by his being a courtier. The lady I pity, and her family. Having done with her, and drunk two glasses of her meade, which she did give me, and so to the Treasurer's Office, and there find my Lord Bruncker (age 47) and Sir W. Pen (age 46) at dinner with Sir G. Carteret (age 57) about his accounts, where I dined and talked and settled some business, and then home, and there took out my wife and Willet, thinking to have gone to a play, but both houses were begun, and so we to the 'Change [Map], and thence to my tailor's, and there, the coachman desiring to go home to change his horses, we went with him into a nasty end of all St. Giles's [Map], and there went into a nasty room, a chamber of his, where he hath a wife and child, and there staid, it growing dark too, and I angry thereat, till he shifted his horses, and then home apace, and there I to business late, and so home, to supper, and walk in the garden with my wife and girle, with whom we are mightily pleased, and after talking and supping, to bed.

Samuel Pepys' Diary. 27th January 1668. Thence to my Lady Peterborough's (age 46), she desiring to speak with me. She loves to be taken dressing herself, as I always find her; and there, after a little talk, to please her, about her [her husband] husband's (age 46) pension, which I do not think he will ever get again, I away thence home, and all the afternoon mighty busy at the office, and late, preparing a letter to the Commissioners of Accounts, our first letter to them, and so home to supper, where Betty Turner (age 15) was (whose brother Frank did set out toward the East Indies this day, his father (age 55) and mother (age 45) gone down with him to Gravesend, Kent [Map]), and there was her little brother Moses, whom I examined, and he is a pretty good scholar for a child, and so after supper to talk and laugh, and to bed.

Samuel Pepys' Diary. 27th January 1668. So to White Hall, and there a Committee of Tangier, but little done there, only I did get two or three little jobs done to the perfecting two or three papers about my Tangier accounts. Here Mr. Povy (age 54) do tell me how he is like to lose his £400 a-year pension of the Duke of York (age 34), which he took in consideration of his place which was taken from him. He tells me the Duchesse (age 30) is a devil against him, and do now come like Queen Elizabeth, and sits with the Duke of York's Council, and sees what they do; and she crosses out this man's wages and prices, as she sees fit, for saving money; but yet, he tells me, she reserves £5000 a-year for her own spending; and my Lady Peterborough (age 46), by and by, tells me that the Duchesse do lay up, mightily, jewells.

Samuel Pepys' Diary. 18th June 1668. After dinner carried her by coach to St. James's, where she sat in the coach till I to my Lady Peterborough's (age 46), who tells me, among other things, her [her husband] Lord's (age 46) good words to the Duke of York (age 34) lately, about my Lord Sandwich (age 42), and that the Duke of York is kind to my Lord Sandwich, which I am glad to hear: my business here was about her Lord's pension from Tangier. Here met with Povy (age 54), who tells me how hard Creed is upon him, though he did give him, about six months since, I think he said, fifty pieces in gold; and one thing there is in his accounts that I fear may touch me, but I shall help it, I hope. So my wife not speaking a word, going nor coming, nor willing to go to a play, though a new one, I to the Office, and did much business. At night home, where supped Mr. Turner and his wife, and Betty and Mercer and Pelling, as merry as the ill, melancholy humour that my wife was in, would let us, which vexed me; but I took no notice of it, thinking that will be the best way, and let it wear away itself. After supper, parted, and to bed; and my wife troubled all night, and about one o'clock goes out of the bed to the girl's bed, which did trouble me, she crying and sobbing, without telling the cause.

Samuel Pepys' Diary. 29th June 1668. Called up by my Lady Peterborough's (age 46) servant about some business of hers, and so to the office.

Samuel Pepys' Diary. 26th September 1668. Could sleep but little last night, for my concernments in this business of the victualling for Sir Prince, so up in the morning and he comes to me, and there I did tell him all, and give him my advice, and so he away, and I to the office, where we met and did a little business, and I left them and by water to attend the Council, which I did all the morning, but was not called in, but the Council meets again in the afternoon on purpose about it. So I at noon to Westminster Hall [Map] and there stayed a little, and at the Swan [Map] also, thinking to have got Doll Lane thither, but elle did not understand my signs; and so I away and walked to Charing Cross [Map], and there into the great new Ordinary, by my Lord Mulgrave's, being led thither by Mr. Beale (age 36), one of Oliver's, and now of the King's Guards; and he sat with me while I had two grilled pigeons, very handsome and good meat: and there he and I talked of our old acquaintances, W. Clerke and others, he being a very civil man, and so walked to Westminster and there parted, and I to the Swan [Map] again, but did nothing, and so to White Hall, and there attended the King (age 38) and Council, who met and heard our answer. I present, and then withdrew; and they sent two hours at least afterwards about it, and at last rose; and to my great content, the Duke of York (age 34), at coming out, told me that it was carried for Prince at 6d. 8d., and 8 3/4d.; but with great difficulty, I understand, both from him and others, so much that Sir Edward Walker told me that he prays to God he may never live to need to plead his merit, for D. Gawden's sake; for that it hath stood him in no stead in this business at all, though both he and all the world that speaks of him, speaks of him as the most deserving man of any servant of the King's in the whole nation, and so I think he is: but it is done, and my heart is glad at it. So I took coach and away, and in Holborne overtook D. Gawden's coach, and stopped and went home, and Gibson to come after, and to my house, where Prince did talk a little, and he do mightily acknowledge my kindness to him, and I know I have done the King and myself good service in it. So he gone, and myself in mighty great content in what is done, I to the office a little, and then home to supper, and the boy to read to me, and so to bed. This noon I went to my Lady Peterborough's (age 46) house, and talked with her about the money due to her Lord, and it gives me great trouble, her importunity and impertinency about it. This afternoon at Court I met with Lord Hinchingbrooke (age 20), newly come out of the country, who tells me that Creed's business with Mrs. Pickering (age 26) will do, which I am neither troubled nor glad at.

Samuel Pepys' Diary. 4th January 1669. Thence up and down the house, and to the Duke of York's (age 35) side, and there in the Duchess's (age 31) presence; and was mightily complimented by my Lady Peterborough (age 47), in my Lord Sandwich's (age 43) presence, whom she engaged to thank me for my kindness to her and her Lord.

Samuel Pepys' Diary. 13th January 1669. So up and by coach to Sir W. Coventry's (age 41), but he gone out, so I to White Hall, and thence walked out into the Park, all in the snow, with the Duke of York (age 35) and the rest, and so home, after visiting my Lady Peterborough (age 47), and there by invitation find Mr. Povy (age 55), and there was also Talbot Pepys (age 22), newly come from Impington, and dined with me; and after dinner and a little talk with Povy about publick matters, he gone, and I and my wife and Talbot towards the Temple [Map], and there to the King's playhouse, and there saw, I think, "The Maiden Queene", and so home and to supper and read, and to bed. This day come home the instrument I have so long longed for, the Parallelogram.

Samuel Pepys' Diary. 4th March 1669. Up, and a while at the office, but thinking to have Mr. Povy's (age 55) business to-day at the Committee for Tangier, I left the Board and away to White Hall, where in the first court I did meet Sir Jeremy Smith, who did tell me that Sir W. Coventry (age 41) was just now sent to the Tower, about the business of his challenging the Duke of Buckingham (age 41), and so was also Harry Saville (age 27) to the Gate-house; which, as [he is] a gentleman, and of the Duke of York's (age 35) bedchamber, I heard afterwards that the Duke of York is mightily incensed at, and do appear very high to the King (age 38) that he might not be sent thither, but to the Tower [Map], this being done only in contempt to him. This news of Sir W. Coventry did strike me to the heart, and with reason, for by this and my Lord of Ormond's (age 58) business, I do doubt that the Duke of Buckingham will be so flushed, that he will not stop at any thing, but be forced to do any thing now, as thinking it not safe to end here; and, Sir W. Coventry being gone, the King will have never a good counsellor, nor the Duke of York any sure friend to stick to him; nor any good man will be left to advise what is good. This, therefore, do heartily trouble me as any thing that ever I heard. So up into the House, and met with several people; but the Committee did not meet; and the whole House I find full of this business of Sir W. Coventry's, and most men very sensible of the cause and effects of it. So, meeting with my Lord Bellassis (age 54), he told me the particulars of this matter; that it arises about a quarrel which Sir W. Coventry had with the Duke of Buckingham about a design between the Duke and Sir Robert Howard, to bring him into a play at the King's house, which W. Coventry not enduring, did by H. Saville send a letter to the Duke of Buckingham, that he had a desire to speak with him. Upon which, the Duke of Buckingham did bid Holmes (age 47), his champion ever since my Lord Shrewsbury's business¹, go to him to know the business; but H. Saville would not tell it to any but himself, and therefore did go presently to the Duke of Buckingham, and told him that his uncle Coventry was a person of honour, and was sensible of his Grace's liberty taken of abusing him, and that he had a desire of satisfaction, and would fight with him. But that here they were interrupted by my Lord Chamberlain's (age 67) coming in, who was commanded to go to bid the Duke of Buckingham to come to the King, Holmes having discovered it. He told me that the King did last night, at the Council, ask the Duke of Buckingham, upon his honour, whether he had received any challenge from W. Coventry? which he confessed that he had; and then the King asking W. Coventry, he told him that he did not owne what the Duke of Buckingham had said, though it was not fit for him to give him a direct contradiction. But, being by the King put upon declaring, upon his honour, the matter, he answered that he had understood that many hard questions had upon this business been moved to some lawyers, and that therefore he was unwilling to declare any thing that might, from his own mouth, render him obnoxious to his Majesty's displeasure, and, therefore, prayed to be excused: which the King did think fit to interpret to be a confession, and so gave warrant that night for his commitment to the Tower. Being very much troubled at this, I away by coach homewards, and directly to the Tower, where I find him in one Mr. Bennet's house, son to Major Bayly, one of the Officers of the Ordnance, in the Bricke Tower [Map]² where I find him busy with my Lord Halifax (age 35) and his brother (age 50); so I would not stay to interrupt them, but only to give him comfort, and offer my service to him, which he kindly and cheerfully received, only owning his being troubled for the King his master's displeasure, which, I suppose, is the ordinary form and will of persons in this condition. And so I parted, with great content, that I had so earlily seen him there; and so going out, did meet Sir Jer. Smith going to meet me, who had newly been with Sir W. Coventry. And so he and I by water to Redriffe [Map], and so walked to Deptford, Kent [Map], where I have not been, I think, these twelve months: and there to the Treasurer's house, where the Duke of York is, and his Duchess (age 31); and there we find them at dinner in the great room, unhung; and there was with them my Lady Duchess of Monmouth, the Countess of Falmouth (age 24), Castlemayne (age 28), Henrietta Hide (age 23) (my Lady Hinchingbroke's (age 24) sister), and my Lady Peterborough (age 47). And after dinner Sir Jer. Smith and I were invited down to dinner with some of the Maids of Honour, namely, Mrs. Ogle (age 17), Blake (age 16), and Howard (age 18), which did me good to have the honour to dine with, and look on; and the Mother of the Maids, and Mrs. Howard (age 43), the mother of the Maid of Honour of that name, and the Duke's housekeeper here. Here was also Monsieur Blancfort (age 28), Sir Richard Powell, Colonel Villers (age 48), Sir Jonathan Trelawny (age 46), and others. And here drank most excellent, and great variety, and plenty of wines, more than I have drank, at once, these seven years, but yet did me no great hurt. Having dined and very merry, and understanding by Blancfort how angry the Duke of York was, about their offering to send Saville to the Gate-house, among the rogues; and then, observing how this company, both the ladies and all, are of a gang, and did drink a health to the union of the two brothers, and talking of others as their enemies, they parted, and so we up; and there I did find the Duke of York and Duchess, with all the great ladies, sitting upon a carpet, on the ground, there being no chairs, playing at "I love my love with an A, because he is so and so: and I hate him with an A, because of this and that:" and some of them, but particularly the Duchess herself, and my Baroness Castlemayne, were very witty. This done, they took barge, and I with Sir J. Smith to Captain Cox's; and there to talk, and left them and other company to drink; while I slunk out to Bagwell's; and there saw her, and her mother, and our late maid Nell, who cried for joy to see me, but I had no time for pleasure then nor could stay, but after drinking I back to the yard, having a month's mind para have had a bout with Nell, which I believe I could have had, and may another time.

Note 1. Charles II wrote to his sister (age 24) (Henrietta, Duchess of Orléans), on March 7th, 1669: "I am not sorry that Sir Will. Coventry has given me this good occasion by sending my Lord of Buckingham a challenge to turne him out of the Councill. I do intend to turn him allso out of the Treasury. The truth of it is, he has been a troublesome man in both places and I am well rid of him" (Julia Cartwright's "Madame", 1894, p. 283).

Note 2. The Brick Tower [Map] stands on the northern wall, a little to the west of Martin tower, with which it communicates by a secret passage. It was the residence of the Master of the Ordnance, and Raleigh was lodged here for a time.

Samuel Pepys' Diary. 2nd April 1669. Up, and by water to White Hall, and there with the Office attended the Duke of York (age 35), and staid in White Hall till about noon, and so with W. Hewer (age 27) to the Cocke (age 52), and there he and I dined alone with great content, he reading to me, for my memory's sake, my late collections of the history of the Navy, that I might represent the same by and by to the Duke of York; and so, after dinner, he and I to White Hall, and there to the Duke of York's lodgings, whither he, by and by, by his appointment come: and alone with him an hour in his closet, telling him mine and W. Coventry's (age 41) advice touching the present posture of the Navy, as the Duke of Buckingham (age 41) and the rest do now labour to make changes therein; and that it were best for him to suffer the King (age 38) to be satisfied with the bringing in of a man or two which they desire. I did also give the Duke of York a short account of the history of the Navy, as to our Office, wherewith he was very well satisfied: but I do find that he is pretty stiff against their bringing in of men against his mind, as the Treasures were, and particularly against Child's' coming in, because he is a merchant. After much discourse with him, we parted; and [he to] the Council, while I staid waiting for his telling me when I should be ready to give him a written account of the administration of the Navy. This caused me to wait the whole afternoon, till night. In the mean time, stepping to the Duchess of York's (age 32) side to speak with Lady Peterborough (age 47); I did see the young Duchess (age 6)¹, a little child in hanging sleeves; dance most finely, so as almost to ravish me, her ears were so good: taught by a Frenchman that did heretofore teach the King, and all the King's children, and the Queen-Mother (age 59) herself, who do still dance well.
