Letter of indulgence of one hundred days, granted to support the construction and decoration of the Chapel of Saints Mary Magdalene and Elizabeth, built for the Dominican "Witte Nonnen" in Leiden.

1 f. (ca. 22,5 x 30,5 cm), on vellum, in Latin, professionally written in black ink. Red wax seal for the larger part preserved, and attached with pins.

In excellent condition.

Very rare indulgence issued by Nicholas of Cusa (1401-1464), Cardinal-Priest of S. Pietro in Vincoli, and papal legate to Germany from 1446. In 1448 he was appointed Cardinal by Nicholas V (Pope 1447-1451). During his "Great Legation" of 1450-1452 he visited numerous churches in North-Western Europe. In Leiden he supported the newly-built chapel of the "White Nuns", inaugurated in 1450. The building was later demolished, and the remains were integrated in the present "Academiegebouw" of Leiden University. There is a problem with the date: the document reads "die mercurij quintadecima mensis Septembr." of 1451. In 1451 wednesdays were either 10 or 17 September. Wednesday 15 September 1452, however, perfectly fits. A scribal error (copy of 1451 text made in 1452)?
