The manuscript also includes works about the Alphonsine Tables, such as canons to the Alphonsine Tables by the 14th-century astronomers John of Saxony, Jean de Lignières (also known as Johannes de Lineriis) and Henricus Selder, and an unattributed explanation of corrections made to the tables for use in Prague, accompanied by a few paragraphs on weather prediction by the Baghdad-born Jewish astronomer and astrologer Māshāʼallāh, who died in the 9th century.
