Liber Saturni, 1478

The book is divided in three parts and is conceived as a dialogue between a teacher (presumably 'Saturnus', but simply called 'the philosopher') and a disciple (whose name, 'Tontulus', is that of the scribe himself). The subscription at the end of the text declares that is has been copied in 1478.
