⁂ A unique compendium of astronomical texts, including significant portions of Regiomontanus' Kalendarium together with other prognostic texts. The various texts have original composition dates that range from the 12th through the 15th century. The Regiomantine text contains small, but significant, differences from the printed version, suggesting that the manuscript precedes the printed text. The contemporary inscription on the rear cover would indicate that the manuscript was perhaps used with the context of the university of Bologna.

A complete listing of the contents is available upon request.

Provenance: Joseff Gregri Da Bologna (early inscription to back cover); Samuel Nerplanck Hoffman (armorial bookplate); Sir Thomas Phillips (inscription to front pastedown).
