To the left of the list of saints’ days are repeating series of letters A - G called Dominical Letters since they help find Sundays (after many calculations). At the far left is a column of Roman numerals i - xix called Golden Numbers to indicate appearances of new moons, & counting ahead 14 days, full moons throughout the year (year + 1; divide by 19; remainder is Golden Number - if zero GN = 19). Finally: each month had 3 fixed points: Kalends (1st day) Ides (middle) & Nones (9th day before Ides). All days in between were counted backwards from these points.

Provenance:   Written for the Use of Paris – Rare inclusion of St. Bruno in the Litany indicates possible ownership by a monk of the Carthusian Monastery of Vauvert (Order of St Bruno), Paris (established 1257, dissolved 1792).
