A leaf from the "Chronicon of Sigebert of Gembloux", a mediaeval chronicler, printed by Henry Estienne (Henry Stephanus) in 1513 at Paris. The pages shown bear the unusual appearance of a Church calendar; there are rubrications, but also events and dates are divided into columns. This volume covered a time from 381 to 1111 A.D. The leaf is marked 126 on the recto side.
