Hugues de Revel (1259-1278). One or two other examples known (see Schlumberger-Blanchet, Orient latin, pp.236-237). The Hospital of Saint John of Jerusalem was established in the Holy City in 1070, before the Crusades, to care for sick and needy pilgrims. The Hospitallers were transformed into a military order in the mid 12th century, and the order's original patron saint, John the Almsgiver, Patriarch of Alexandria, was replaced by John the Evangelist. Under the direction of a Grand-Master, the brothers were divided into knights, sergeants, and clerics. Their distinctive badge was a white cross, worn on their tunics over their armour.
