Franciscus Sirigattus
Abreviatio super Quadripartito Ptholomei


‘(Paris, BnF, lat. 7433) Abreviatio F<rancisci> Sirigatti super Quadripartito Ptholomei. Scientia stellarum est ars a principiis certis aliarum scientiarum proveniens, quibus ea quae accidunt possunt sciri — et dabimus cuilibet signo duos dies et horas 8. Finis quarti et ultimi libri Quadripartiti…’ (end of line deleted).


A summary of the complete text of the Quadripartitum, probably in Aegidius de Tebaldis’s translation (Haly is quoted f. 16v and 26r), with notes by the author, who also quotes Albumasar and Hermes.


The only surviving MS is Franciscus Sirigattus’s autograph and was copied in Florence around 1492.
