LJS 472 - [Ḥeshbon mahalkhot ha-kokhavim]This manuscript is a 15th-century copy of the second part of a 12th-century two-part treatise, on astronomy (the first part, not present in this manuscript, discussed geography). It includes computations for solar and lunar eclipses between 1135 and 1136. Numerous marginal notes were preserved when the manuscript was trimmed, leaving tabs that have been folded in. It was possibly written in Spain in the 15th century. Click here for additional information, here for the facsimile, and here for the video orientation. -- source link
