The buildings of the Order, at first meagre, were finally enlarged to cover a square, nearly 500 ft. on each side, with one side on the Via Dolorosa and another fronting the Bazaar, and all a little south of the Church of the Holy Sepulchre. Nearby were other churches and hospices. This was the arrangement before the establishment of the kingdom of Jerusalem in 1099. During the next century the Order, under Raymond du Puy, had enlarged the church of St. John Eleëmon into the conventual church of St. John Baptist, while along the south of the square above mentioned ran an excellent building, the hospital of St. John. When Saladin recaptured Jerusalem, in 1187, this church was converted by the Turks into a mad-house, known as the "Muristan," this being finally ceded to Germany in 1869. From the new kingdom of Jerusalem the Hospitallers obtained a constitution, and the Gerard above mentioned was made their first "Master." He was succeeded in 1118 by du Puy, while Baldwin II was the Latin King of Jerusalem. The Hospital had been recognized by the Archbishop of Caesarea in 1112, and had widely extended its sphere of usefulness. It was King Baldwin who was anxious to stamp upon the Order a military character, similar to that conferred upon the Order of the Temple in 1130. This was natural since the kingdom was isolated, surrounded by fanatic enemies and always beset by and in danger from them. Thus the necessities of the times and the environment made it requisite that all who were able should bear arms, and coöperate for mutual defence. Thus it came about that the Order was divided into three divisions, the first in rank being the Knights of Justice, each of whom must be of noble rank or birth, and have received the accolade of knighthood from secular authority. The second division comprised the ecclesiastics, who were later divided into two grades, the Conventual Chaplains, who were assigned to duty at headquarters, and the Priests of Obedience who served other priories and commanderies in various parts of Europe. The third grade were the Serving Brothers, also divided into the Servants at arms or Esquires, and the Servants at office. The Servants at arms attended the Knights of Justice as their Esquires, and might eventually become eligible to the first division. The Servants at office were little if anything more than menials or domestics. Even these latter, however, possessed certain privileges and emoluments which made admission to this grade advantageous to men of humble origin and faculties. The dress of the Order was a black robe with cowl, having a white linen cross of eight points over the left breast, and was at first worn by all. Later, under Pope Alexander IV, the fighting knights wore their white crosses upon a ground gules.
