Grayson from St Mary's Abbey. It is an octavo volume and was printed on 8 November 1526 by Thielmann Kerver in Paris. Brother Grayson was first noted at the Abbey in 1528 but was absent from its pension list at the time of the Dissolution in 1539. The Anonimalle Chronicle The Anonimalle Chronicle is an important chronicle whose scope extends from the legendary Brutus to 1381. It was composed in Anglo-Norman by an anonymous monk of St Mary's Abbey towards the end of the 14th century. It includes the most detailed surviving description of a medieval parliament and a well-informed account of the Peasants' Revolt of 1381; these are likely to have been written by eyewitnesses and later incorporated into the chronicle. The body of the chronicle from Brutus to the year 1307 has been described as a variant of the Brut Chronicle, but there are considerable differences (e.g. the chronicler shows an interest in early ecclesiastical history which the Brut does not). From 1307 to 1333 it follows the main Brut tradition more closely though it demonstrates a marked London interest. After 1333 the chronicle is an individual account probably drawing on sources originating in London. The manuscript was known to the 16th-century antiquaries Francis Thynne and John Stow; its title derives from Thynne's description of it. It afterwards passed through the hands of various owners until it was found in the possession of the Ingilby family of Ripley Castle in 1920. The section from 1333 to 1381 was edited by V. H. Galbraith and published in 1927. In 1982 it was acquired by the Brotherton Collection, at the University of Leeds. Another partial edition appeared in 1991 in the form of an edition and translation of the chronicle from 1307 to 1334 by Wendy Childs and John Taylor. Excavations in the Abbey precinct The Yorkshire Museum, built for the Yorkshire Philosophical Society, stands in part of the abbey cloister; parts of the east, south and west cloister walls were temporarily excavated in 1827–29 preparatory to digging the museum's foundations. The relationship between the Museum and abbey is historically quite intimate as part of the richly carved chapter house vestibule (–1307) survives incorporated into Tempest Anderson Hall lecture theatre (1911–12). These walls and part of the warming house are retained in the Museum as part of the Medieval gallery display. Excavations of the chapter house were undertaken in 1912
