This composite manuscript of mainly astrological-astronomical content includes a journal of weather observations kept over seven years, the so-called Basler Wettermanuskript. It records meteorological observations in daily entries from January 1, 1399 until March 21, 1406, without a single gap. Towards the end of the journal, the entries become more schematic, until finally they transition to tables of the positions of the planets with only occasional comments on the weather. The volume is from the Dominican Convent of Basel. (gam/flr)

This manuscript, written in a 13th century textura, was the property of the cleric and historian Dietrich von Niem (1340-1418), who provided it with numerous marginal notes. The volume, which was passed on to the Carthusian Monastery of Basel, contains, among others, Seneca's Naturales quaestiones, the discussion Cur deus homo? by Anselm of Canterbury, and the astrological work De radiis stellarum by the Arab philosopher and scientist Alkindi. It also contains the article De probatione virginitatis beatae Mariae from the so-called "Suda", a Byzantine encyclopedia widely used in the Latin translation by Roberto Grosseteste. (flr)
