Giovanni wrote three works about Padua in Latin between 1314 and 1337, collectively known as the Liber ludi Fortune (Book of the Fortune's game).[3] The order in which they appear in manuscripts which carry all three[4] is:
- De aedificatione urbis Patavie[5] (On the founding of the city of Padua)
- Visio Egidii regis Patavie (Vision of Egidius king of Padua)
- Liber de generatione aliquorum civium urbis Padue, tam nobilium, quam ignobilium (Book of the genealogy of some citizens of the town of Padua, both nobles and commoners)
De aedificatione is the shortest of the three. It describes how a mythical Paduan king named Dardanus defeated Tartarus, king of the Tartars. He then goes to fight in the Trojan War and is killed by Antenor, who founds Altino and refounds Padua after an earthquake.
The Visio Egidii belongs to the medieval genre of urban description. It is framed, however, as a prophetic vision of the legendary king Egidius in the time of Attila the Hun. It was written between 1314 and 1318. It describes, in succession, the gates, walls and secular buildings, ending with the town hall and the adjacent market squares. It does not mention any religious buildings.
De generatione is Giovanni's major work. It is divided into four books in the oldest manuscript, but this division is not followed in all copies. It gives overviews of both major and minor families of the region, beginning with the House of Este and other powerful families and ending with over a hundred families of the lowest (popolano) rank, among them the Scrovegni.
