Butler's Lives of the Saints: June

This original work has been updated for it is most urgent that a thorough revision be undertaken, completely rewritten and with substantial amendments to the selection of entries. These amendments have been made necessary, first by the major reform of the Roman Calendar, and by the unprecedented number of canonizations and beatifications of recent decades. To these factors must be added the ongoing revision of the Roman Martyrology in progress at the Congregation of Divine Worship in Rome, which has altered a number of dates for commemoration, and which this new revision follows.
