It took place in the island of Rhodes. This Greek isle had become the home of the Knights of St. John, or Hospitaliers, an order of sworn brethren who had arisen at the time of the Crusades. At first they had been merely monks, who kept open house for the reception of the poor penniless pilgrims who arrived at Jerusalem in need of shelter, and often of nursing and healing. The good monks not only fed and housed them, but did their best to cure the many diseases that they would catch in the toilsome journey in that feverish climate; and thus it has come to pass that the word hospitium, which in Latin only means an inn, has, in modern languages, given birth, on the one hand, to hotel, or lodging house, on the other, to hospital, or house of healing. The Hospital at Jerusalem was called after St. John the Almoner, a charitable Bishop of old, and the brethren were Hospitaliers. By and by, when the first Crusade was over, and there was a great need of warriors to maintain the Christian cause in Jerusalem, the Hospitaliers thought it a pity that so many strong arms should be prevented from exerting themselves, by the laws that forbade the clergy to do battle, and they obtained permission from the Pope to become warriors as well as monks. They were thus all in one--knights, priests, and nurses; their monasteries were both castles and hospitals; and the sick pilgrim or wounded Crusader was sure of all the best tendance and medical care that the times could afford, as well as of all the ghostly comfort and counsel that he might need, and, if he recovered, he was escorted safely down to the seashore by a party strong enough to protect him from the hordes of robber Arabs. All this was for charity's sake, and without reward. Surely the constitution of the Order was as golden as its badge--the eight-pointed cross--which the brethren wore round their neck. They wore it also in white over their shoulder upon a black mantle. And the knights who had been admitted to the full honors of the Order had a scarlet surcoat, likewise with the white cross, over their armor. The whole brotherhood was under the command of a Grand Master, who was elected in a chapter of all the knights, and to whom all vowed to render implicit obedience.
