Arithmetice Lilium Triplicis Practice (The threefold lily of practical arithmetic) presents basic arithmetic operations such as addition and multiplication for whole numbers and fractions.

These works constitute the city’s most famous and long-lasting contribution to Islamic and world civilization. This work (date unknown) explains mathematical calculations and their use in astronomy and astrology. The final portion of the manuscript is missing.

Book on Geometry, Practice, and Patterns
This landscape-shaped printed work is the first treatise on tailoring published in Spain. It paved the way for other such works in the late 16th century and early 17th century.

In his dedication, to a theologian called Tejada, he describes "this, my small work, something brand new, never seen so far in our Spain." The usefulness of the work was confirmed by Hernan Gutierrez, tailor to the princess of ...
