[Antiphonar] Choir book. 15th century with four musical leaves. Hand writing on parchment.

Leather binding on 2 wooden covers with iron fittings. Binding and spine are worn. 76x53 cm. 4 leaves with musical notations (70x49 cm.) in parchment; black-red-blue. Leaves have been restored in a sloppy way.

Medieval choir books are exceptionally large. This is because several clergymen had to read from one book simultaneously and often from a large distance.
