Dr. Lois Drewer served as a specialist in Byzantine art at the Index of Medieval Art from 1988 until her passing in 2011. Among the projects she left behind was the Calendar of Saints in Byzantine Manuscripts and Frescoes that became the basis for this online tool. Through it, she hoped to make the study of Byzantine saints more accessible to students and scholars of all aspects of medieval studies.
The saints represented here are ordered by date, according to feast days in the Constantinopolitan calendar. Each entry consists of a brief identification of the saint, links to standard reference tools, and concise descriptions of calendar illuminations and frescoes for that feast. The database also permits searching by saint, type, costume, narrative scene, and iconography.
The database was extensively updated in 2025, and we are pleased to make it available once more in Dr. Drewer’s memory. We hope that many will find it a useful tool.
