Content Short additions to the Almagest, consisting mainly of tables (shadow tables, tables of months) and a note on the precessional increment to the star catalogue for 1530.
Origin These additions were made by Luca Gaurico to his own edition of Ptolemy’s Almagest in the translation of George of Trebizond (A.1.4), published in Venice in 1528. Gaurico also left a few annotations in the margins of the text of the Almagest (ed. Venice 1528 – in the subsequent editions of 1541 and 1551, these annotations have been inserted into the text in italics and with the mention ‘Gauric<us>’).
