or Restoro d'Arezzo
was an Italian monk of the thirteenth century
, author of the Composizione del Mondo
of c. 1282.
This is the first astronomical work to be written in Italian (Tuscan). It contains also, as its title (The Composition of the World) suggests, geological theories: these covered the internal structure of a spherical shell Earth, fossils, and erosion, amongst others.
It has been claimed that Dante was familiar with Ristoro’s work. Dante in the Quaestio de Aqua et Terra dated to 1320 did consider related matters.
