I HAVE HAD THE PLEASURE recently of looking through the expanded edition of the Gesangüchlein Geistlicher Psalmen, Hymnen, lieder und gebet . . . (Bonn, 1561). It attracts attention from the very start. Near the front of the book is a quite full Kalendar of saints and festivals, so much so that one is at first made to wonder whether or not it is a Lutheran book. Lutheran hymnals and cantionals of the period tend to be a little sparing on the Kalendar, usually preferring to keep only festivals suggested by Luther, et al., or found only in Scripture, or not too much associated with any local cult or relic. The purpose here seems to have been to have a commemoration or festival for each day of the year. The Kalendars months have phrases to the left of the arabic numerals which are meant to be used a mnemonic device. Following the months are tables and more mnemonic verses for the days and seasons, Embertides, etc. There are also nice illustrations of a dominical letter wheel and a golden number wheel.
