Letters and Papers 1533. 18 May 1533. 508. Tomorrow the duke of Norfolk's (age 60) horses and some of his company will leave this. He himself will follow in six days, to be at Nice at the beginning of July. As for news, the Pope's agent, who was here about the convocation of the Council, was referred from the court of France to this court for an answer to this charge, and the English have sent him back to the said court, remitting everything to the will of the French king. The King's Council say that the Pope is only trifling in this matter, and has no more wish for a Council than they have. The Pope's agent has been very well received with a present of 300 cr. They made court some days to the Nuncio to give the people to understand the intelligence they had with the Pope. They had the Nuncio here resident for this and other matters quite at their command, and he has done very poor service in the Queen's affair. Nothing is known yet to have been done by the French ambassador, who has gone to Scotland for the peace. Since he left here, he has received many letters from his own court; which, I suspect, is owing to the urgency of the English, who desire peace very much. There have been here, for eight days, two young Frenchmen, who, the day before yesterday, returning from court, where one was made a knight, came to visit me with the French ambassador. They are sent hither by the grand master and admiral of France to be installed in the Chapel of the Order of the Garter at Windsor, in the name of those lords.

Letters and Papers 1533. 18 May 1533. Vienna Archives. 508. Chapuys (age 43) to Charles V.

Although the King's Council had promised me an answer to my letters within three days, they delayed to call me for more than six. On Tuesday last the duke of Norfolk (age 60) and others invited me to dinner, which I thought it right to decline under the circumstances, especially not to increase the suspicion that your Majesty has consented to this detestable proceeding. After dinner I went to them; and there, for innumerable reasons, they wished to persuade me that I ought not to interfere with the jurisdiction of the archbishop of Canterbury, both on account of their late law, and also for the insufficiency of my power, against which they raised several objections. Having fully replied to them on these matters, they, instead of answering me, begged me to consider the little good, and, on the other hand, the danger, that would arise from what it was proposed to do. I showed them again the utility of it, and the necessity which compelled me to proceed according to my charge; and both on this and on the other matters we had a long conversation, of which it is needless to report the tenth part, as all the points depended one upon another.

Letters 1536. Has just received the Emperor's letters of the 18th ult., with enclosures, which he will use as instructed. Will immediately report how the King takes everything. Has heard that the King, before the said bailiff's arrival, took in very good part the Emperor's proposal. So Briant told Mrs. Semel [Jane Seymour (age 27)] and other ladies on the day the King sent to inform her of the putain's condemnation; and though Brian is French in his leanings, be does not forbear to praise your Majesty in these matters, and to abuse and laugh at the French, who had made a foolish and shameful reply about the combat between your Majesty and the king of France. Cannot write more fully about the King's inclination to negotiate. Cromwell puts him continually in hope, especially by what has happened to the Concubine. Will understand matters better when he has spoken with the King, which he will do as soon as he can. Must not omit to mention that although the King at Easter pressed him strongly for the four articles in writing, he has since praised Chapuys for his refusal and for his further diplomacy; and Cromwell, the same day, admitted to him that the request for those articles in writing was not justified by any suspicion. On Chapuys asking what could have turned the King so suddenly from the intention he had so persistently declared to Chapuys, Cromwell could give no other reason except that the King had taken some suspicion of himself by reason of the letters your Majesty had written to him.

Letters 1536. 18 May. Vienna Archives. 901. Chapuys (age 46) to Antoine Perrenot.

As I hear that letters from England are opened at Calais, you will have more trouble in deciphering several things which but for this might be written clear. I have no news to add to what I write to His Majesty, except to tell you something of the quality of the King's new lady [Jane Seymour (age 27)], which the Emperor and Granvelle would perhaps like to hear. She is sister of one Edward Semel (age 36), "qua este a sa majesty," of middle stature and no great beauty, so fair that one would call her rather pale than otherwise. She is over twnty-five years old. I leave you to judge whether, being English and having long frequented the Court, "si elle ne tiendroit pas a conscience de navoir pourveu et prevenu de savoir que cest de faire noces¹." Perhaps this King will only be too glad to be so far relieved from trouble. Also, according to the account given of him by the Concubine (age 35), he has neither vigour nor virtue; and besides he may make a condition in the marriage that she be a virgin, and when he has a mind to divorce her he will find enough of witnesses. The said Semel [Jane Seymour] is not a woman of great wit, but she may have good understanding (un bel enigm, qu. engin?). It is said she inclines to be proud and haughty. She bears great love and reverence to the Princess. I know not if honors will make her change hereafter. The news you wrote on the 22nd ult. touching Haurain² and the Sophi are very good, and I pray God your wish may be accomplished towards those who are in grief. London, 18 May 1536.Fr., from a modern copy, pp. 2.

Samuel Pepys' Diary. 18 May 1663. Up and after taking leave of Sir W. Batten (age 62), who is gone this day towards Portsmouth, Hampshire [Map] (to little purpose, God knows) upon his survey, I home and spent the morning at dancing; at noon Creed dined with us and Deane (age 29) of Woolwich, and so after dinner came Mr. Howe, who however had enough for his dinner, and so, having done, by coach to Westminster, she to Mrs. Clerke and I to St. James's, where the Duke being gone down by water to-day with the King (age 32) I went thence to my Lord Sandwich's (age 37) lodgings, where Mr. Howe and I walked a while, and going towards Whitehall through the garden Dr. Clerk and Creed called me across the bowling green, and so I went thither and after a stay went up to Mrs. Clerke who was dressing herself to go abroad with my wife.

Samuel Pepys' Diary. 18 May 1663. Thence for an hour Creed and I walked to White Hall, and into the Park, seeing the Queen (age 24) and Maids of Honour passing through the house going to the Park. But above all, Mrs. Stuart (age 15) is a fine woman, and they say now a common mistress to the King (age 32)¹, as my Baroness Castlemaine's (age 22) is; which is a great pity.

Note 1. The King said to 'la belle' Stuart, who resisted all his importunities, that he hoped he should live to see her "ugly and willing" (Lord Dartmouth's note to Burnet's "Own Time", vol. i., p. 436, ed. 1823).

Samuel Pepys' Diary. 18 May 1665. Up, and with Sir J. Minnes (age 66) to the Duke of Albemarle (age 56), where we did much business, and I with good content to myself; among other things we did examine Nixon and Stanesby, about their late running from two Dutchmen¹ for which they are committed to a vessel to carry them to the fleete to be tried. A most fowle unhandsome thing as ever was heard, for plain cowardice on Nixon's part.

Note 1. Captain Edward Nixon, of the "Elizabeth", and Captain John Stanesby, of the "Eagle". John Lanyon wrote to the Navy Commissioners from Plymouth, Devon [Map], May 16th: "Understands from the seamen that the conduct of Captains Nixon and Stanesby in their late engagement with two Dutch capers was very foul; the night they left the Dutch, no lights were put out as formerly, and though in sight of them in the morning, they still kept on their way; the Eagle lay by some time, and both the enemy's ships plied on her, but finding the Elizabeth nearly out of sight she also made sail; it is true the wind and sea were high, but there were no sufficient reasons for such endeavours to get from them". (Calendar of State Papers, Domestic, 1664-65, p. 367). Both captains were tried; Nixon was condemned to be shot but Stanesby was cleared, and Charnock asserts that he was commander the "Happy Return" in 1672.

Samuel Pepys' Diary. 18 May 1665. Thence with the Duke of Albemarle (age 56) in his coach to my Lord Treasurer (age 58), and there was before the King (age 34) (who ever now calls me by my name) and Chancellor (age 56), and many other great Lords, discoursing about insuring of some of the King's goods, wherein the King accepted of my motion that we should; and so away, well pleased.

Samuel Pepys' Diary. 18 May 1666. At noon had them and carried them home, and there dined with great content with my people, and within and at the office all the afternoon and night, and so home to settle some papers there, and so to bed, being not very well, having eaten too much lobster at noon at dinner with Mr. Hollyard (age 57), he coming in and commending it so much.

Samuel Pepys' Diary. 18 May 1668. Thence to my tailor's, and there did find Mercer come with Mrs. Horsfield and Gayet according to my desire, and there I took them up, it being almost twelve o'clock, or a little more, and carried them to the King's playhouse, where the doors were not then open; but presently they did open; and we in, and find many people already come in, by private ways, into the pit, it being the first day of Sir Charles Sidly's (age 29) new play, so long expected, "The Mullberry Guarden", of whom, being so reputed a wit, all the world do expect great matters. I having sat here awhile, and eat nothing to-day, did slip out, getting a boy to keep my place; and to the Rose Tavern, and there got half a breast of mutton, off of the spit, and dined all alone. And so to the play again, where the King (age 37) and Queen (age 29), by and by, come, and all the Court; and the house infinitely full. But the play, when it come, though there was, here and there, a pretty saying, and that not very many neither, yet the whole of the play had nothing extraordinary in it, at all, neither of language nor design; insomuch that the King I did not see laugh, nor pleased the whole play from the beginning to the end, nor the company; insomuch that I have not been less pleased at a new play in my life, I think. And which made it the worse was, that there never was worse musick played-that is, worse things composed, which made me and Captain Rolt (age 39), who happened to sit near me, mad. So away thence, very little satisfied with the play, but pleased with my company. I carried them to Kensington, to the Grotto, and there we sang, to my great content, only vexed, in going in, to see a son of Sir Heneage Finch's (age 40) beating of a poor little dog to death, letting it lie in so much pain that made me mad to see it, till, by and by, the servants of the house chiding of their young master, one of them come with a thong, and killed the dog outright presently.

John Evelyn's Diary. 18 May 1688. The King (age 54) was so far incensed at this address, that he with threatening expressions commanded them to obey him in reading it at their perils, and so dismissed them.

John Evelyn's Diary. 18 May 1688. King (age 54) enjoining the ministers to read his Declaration for giving liberty of conscience (as it was styled) in all churches of England, this evening, six Bishops, Bath and Wells (age 50), Peterborough (age 60), Ely (age 50), Chichester (age 64), St. Asaph (age 60), and Bristol (age 38), in the name of all the rest of the Bishops, came to his Majesty to petition him, that he would not impose the reading of it to the several congregations within their dioceses; not that they were averse to the publishing it for want of due tenderness toward dissenters, in relation to whom they should be willing to come to such a temper as should be thought fit, when that matter might be considered and settled in Parliament and Convocation; but that, the Declaration being founded on such a dispensing power as might at pleasure set aside all laws ecclesiastical and civil, it appeared to them illegal, as it had done to the Parliament in 1661 and 1672, and that it was a point of such consequence, that they could not so far make themselve parties to it, as the reading of it in church in time of divine service amounted to.

Section I Tumuli 1844. On the 30th of July, 1844, was re-examined a barrow [Map] upon the Oldham Farm, Middleton, which was unsuccessfully opened by Mr. William Bateman, on the 18th of May, 1825, nor was this second investigation much more interesting, as the barrow proved in most respects the same as the one on Ringham Lowe [Map], which is within half a mile of the one in question. There were the remains of a large fire visible in the centre of this mound, upon the level of the undisturbed soil, where were also some pieces of sandstone and some quartz pebbles, neither of which are to be found in the neighbourhood. The only articles of human origin were several pieces of kneaded clay, partially hardened by the fire, and a broken piece of coarse pottery of very hard texture.
