But the brotherhood did leave its share of concrete historic record. Perhaps most fascinating: “The Rule of the Templars,” which outlined a detailed code of conduct governing every aspect of daily life, including clothing (spartan), meals (mostly silent), sleeping arrangements (austere), social restrictions (ample). There’s a good-sized section on penance, which was especially important for maintaining the order’s all-important discipline. The first draft, composed in 1129, dictated 68 rules designed to keep Templar knights on a tight leash, reflecting their vows of poverty, chastity and especially obedience. As the order grew bigger, more wealthy and more militarized, its disciplinary code expanded to several hundred rules and became increasingly complex.
