The World Digital Library has posted a digital version of the Book on Geometry, Practice, and Patterns by Juan de Alcega. Published in 1580, the book offers techniques for ordering lengths of fabric based on the measurement of the "ell."

The book also provides "135 traças (patterns) used to make clothing for men, women, clergy, commanders of military orders, suits for jousts and reed games, and even flags of war." The landscape format shows optimal layout of patterns.
