Thomas of Eccleston
Thomas of Eccleston was a thirteenth-century English Franciscan chronicler. He is known for De Adventu Fratrum Minorum in Angliam. It runs from 1224, when Franciscan friars first came to England, under Agnellus of Pisa, to about 1258. He styles himself simply "Brother Thomas" and John Bale seems to have first given him the title "of Eccleston".
Life
He entered the Order of Friars Minor in about 1232 or 1233 and was a student at Oxford between 1230 and 1240. After 1240, he was at the London monastery, though he held no office there.The chronicle
The De Adventu is a collection of notes rather than a finished work. Incidentally it throws some light on the trend of early Franciscan events and thought in general.
For a period of twenty-six years, Eccleston was busy collecting material for his chronicle, which he based on personal knowledge, interviews, and documents no longer extant. He described the “heroic period” of the Franciscan movement in England. His chronicle lacks dates, is weak on chronological presentation, and gives preference to England, but is considered accurate and reliable in the content related to the Friars Minor in England.
