Question of the Water and the Land (Quaestio de aqua et terra)
This book is in Latin.
Dante’s academic disputation at Verona on 20 January 1320 on the form and position of the two elements, water and earth: whether water in its sphere stands higher than the land. The work survives only in a Venice print of 1508 and its authenticity was long debated; most scholars now accept it. Text of La Wikisource.
