Basil II
The Menologion of Basil II (also called Menologium of Basil II, Menology of Basil II) is an illuminated manuscript designed as a church calendar or Eastern Orthodox Church service book ("menologion") that was compiled c. 1000 AD, for the Byzantine Emperor Basil II (r. 976–1025). It contains a "synaxarion", a short collection of saints' lives, compiled at Constantinople for liturgical use, and around 430 miniature paintings by eight different artists. It was unusual for a "menologion" from that era to be so richly painted. It currently resides in the Vatican Library (Ms. Vat. gr. 1613).
