Togheter the 3 volumes in First Edition from Dugdale's monumental study of the edifices of English monasticism. The first volume of Monasticon Anglicanum appeared in 1655 (with Dudgale & Dodsworth named as joint authors) with subsequent volumes coming in 1661 and 1673. "It gave the history of the various orders in England, and an account of all individual monastery, were printed in full, and all known benefactions of land made to the monastery were set down. Monasticon Anglicanum established for the first time the importance of charters as a primary source for the writing of medieval history and as source of understanding the legal practice of earlier centuries and aspects of the feudal system relating to conditions of tenure. Equally it established for the first time since the Reformation the importance of monasteries and the scale of their territorial possessions". (ODNB)
