The diary extends from 1550 to 1563; it is couched in language and orthography which denote deficient education even for that time, but is valuable as a reliable record of events, interesting as a picture of the age, and amusing from its quaint style. Strype made great use of it in the way of quotation in his Ecclesiastical Memorials, as a trustworthy authority. The MS. is in the Cotton collection. It suffered in the fire at Sir Robert Cotton's house, Westminster, and now remains in a fragmentary form, being much scorched and burnt at the edges. In the year 1848, it was published by the Camden Society, edited by Mr. John Gough Nichols, F.S.A., with a glossary, notes, etc.

The following extracts from the diary give a vivid picture of London 300 years ago; the tone of public opinion, and the turbulence of the time, with the picturesque accessories of pageants and processions, and the less pleasing but ever present spectacles of whipping, pillorying, hanging, quartering, and burning of heretics and rebels.

1. The restored Papal rule. Queen Mary ascended the throne in 1553, and immediately reversed all the doings of her father and brother in matters of religion. Thus writes Machyn: —

"August 5th, 1553. Cam out of the Marselsay the old Bishop of London, Bonar, & dyvers bysshopes bryngyng him unto home ye plasse at Powlces, & doctor Coke whent to the same plass yn the Marselsey that the bysshope was in."

February 12th, 1573-4. After Wyatt's rebellion "there was mad at evere gate in Lundun a newe payre of galous, & set up 11 payre in Cheapside; 11 payre in Fletstrett, 1 in Smythfyld, 1 in Holborne, 1 at Ledyn-hall, 1 at Sant Magnus, London Bridg, one at Refer Allay Gatt, one at Sant George's, 1 at Borunsay (Bermondsey) strett, 1 on Towr hylle, 1 payre at Charyng Crosse, and 1 payre besyd Hyd Parke corner." The executions took place on the 14th, and "on the iiii daye of junii wasse all the galus in London plokyd done in all plases."

September 23rd, 1554. "Dyd pryche doctur Rud at Powlle's Crosse, and he recantyd and repentyd that he ever was mared (married) and sayd openly that he cold not mare by God's law."

September 15th, 1556. "A sermon was preached at Powlle's," when was declared, "the Popes jubele and pardon from Rome, and as mony as wyll rescyffe ye pardon so to be schryff (shrived) and fast three days in on weeke and to rescyff the blessed sacrament, the next Sunday affter, clen remyssyon of alle ther synnes tossyens quossyens (? toties quoties) of all that ever they dyd."

March 25th, 1556. A grand day at Bow Church. "Our Lady Day, the Annunsyasyon, at Bow Chyrch was hangyd wyth cloth of gold and with rich hares (arras) and cossens (cushions) for the commyng of my Lord Cardenal Pole. Ther dyd the Bysshop of Vossetr (Worcester) syng he (high) masse, mytyred, and ther were dyver bysshopes, as the B. of Ely, London, and Lynkkolne, and the Yerle of Pembroke, and Ser Edw. Hastynges, the Master of the Horse, and dyvers odur nobul" (unfinished).

It seems there were those in London who did not approve of the Queen's proceedings, and even resorted to violent measures, besides Sir Thomas Wyatt and his followers. 1554-5. "The 17th day of Feybuary, at about mydnight, ther wer serten lude feylows cam unto Sant Thomas of Acurs, and over the dore ther was set the ymage of Sant Thomas, and ther they brake ys neke and the tope of ys crosier, the wych was mad of fre stone. With grett sham was yt done." On March 14th, the same year, "Serten velyns dyd breke the neke of the ymage of Sant Thomas of Cantarbere, and on of ys arms broke."

The next day was issued, "A proclamassyon that wo so ever cold bring word to the mare who dyd breke ys neke shuld have C. (100) croones of gold for his labur." He does not state whether the iconoclasts were discovered. There are numberless entries also, such as the following: "July 24th, 1553, was a felow set in the pelere [pillory] for speykyng agaynst the good Quen Mare." September 17th, 1557, "Ther whent out of Newgatt unto Yylyngton beyond the buttes, towards the cherche, in a valey, to be borned, four—three men, on woman, for herese duly—two of them was man and wyfe dwellyng in Sant Dunstan's in the East." November 12th, 1558. "Saturday, ther was a woman sett on the pelere for sayhing that the Quen was ded and her Grace was not ded."
