Basel, Universitätsbibliothek, F IV 17 : Ovidio Naso, Heroides, cum glossa Guilelmi Aurelianensis

This small-format, almost square 14th century Ovid manuscript contains the Heroides accompanied by the commentary of William of Orléans (Guilelmus Aurelianensis, around 1200). An older erased note of ownership suggests a French origin; Johannes Heynlin bequeathed this manuscript to the Carthusian Monastery of Basel.
