The Chronicle of Mount St. Agnes is the only work of Thomas à Kempis of which no English translation has yet appeared, and even in its original form the book is not readily accessible to readers, since the only text is that published by Peter and John Beller of Antwerp in 1621. The ordinary collections of the works of à Kempis do not contain the Chronicle, although there is no doubt as to the authenticity of the book, which is of considerable importance to students of the movement known as “The New Devotion,” and to those who are interested in the Brotherhood of the Common Life. The last nine pages of the Latin text have been added by an anonymous writer, and carry on the chronicle from the year 1471, in which à Kempis dies, to 1477, but since this portion of the book is included in the first printed edition, and contains a notice of the author written by a contemporary member of the community, I have included the addition in the present translation of the Chronicle.
