In the year 1259 the Pope, Alexander IV., finding that men of noble birth objected to be habited as were the “serving brothers,” ordained that the knights on a campaign should wear a “sopraveste” of scarlet embroidered with the cross in white; further, that should any knight abandon the ranks, and fly from the battle, he should be deprived of his order and his habit. The form of government was purely aristocratic, all authority being vested in the Council, of which the Grand Master was the chief, the case of an equal division of opinion being provided for by giving to the Grand Master the casting vote. There were in the Order certain aged knights who were called “Preceptors,” who, under authority delegated to them by the Council, administered the estates and funds accruing, and also paid for the hire of such soldiers or “seculars” whom the Knights took into their service.
Incidentally, it may be mentioned that the establishment of the Knights of St. John led to the foundation of the famous Order of the Knights Templars. In 1118 Hugues de Payens, Geoffrey de St. Aldemar, and seven other French noblemen, whose hearts were touched by the sufferings which the pilgrims underwent in their journey to Jerusalem, formed themselves into a society with the object of the protection of these inoffensive persons on their transit from the coast inland. Hugues de Payens, received in audience by Pope Honore II., was sent by the Pontiff to the Peers of the Council, then assembled at Troyes in Champagne; the Council approving of so charitable an enterprise, the Order was formed, and Bernard, known as “Saint” Bernard, drew up the code of regulations by which it was to be governed. The movement spread, and many princes and nobles returned to the Holy Land in the train of de Payens and his companions.
So famous did the Order of St. John become, that in 1133 Alfonzo, King of Navarre and Arragon, who called himself Emperor of Spain, carried his zeal so far as to bequeath to the knights his kingdoms of Navarre and Arragon: this, however, was naturally and hotly contested in these places, and Raimond Dupuy, who attended a Council to regulate the matter, was content to compromise on certain lands and benefits being allocated to those whom he represented.
On August 15th, 1310, the knights, under the Grand Master, Fulke de Villaret, conquered the Island of Rhodes and established themselves there, and from this time onward, while they held the island, were known as the Knights of Rhodes. No sooner were the knights firmly established in Rhodes and the fortifications placed in a proper state of repair, than a tower was built on the highest point of the island, of great height, from which a view could be obtained of the sea and the surrounding islands, and from which information could be signalled as to the movements of any vessels which were observed. It was then decided to fortify the small island of Cos or Lango in the vicinity, as it contained an excellent harbour; a fortress, planned by the Grand Master himself, was erected on the island, a knight was left in command, and we are told that under the successors of de Villaret—himself twenty-fourth Grand Master—the island, which was very fertile, flourished exceedingly, producing much fruit and some most excellent wine.
