It has been truly said that temples were the first hospitals, and priests the earliest physicians.[97:1] In the temples of Esculapius, in Greece, a main object of the various mystic rites was to exert a powerful influence on the patient's imagination. This was supplemented by practical therapeutic and hygienic treatment, such as baths, friction of the skin, and a strict diet. These primitive sanatoria were built in places carefully chosen for their salubrity of climate and healthful environment. Doubtless their founders were actuated by a belief that Esculapius was ever ready to help those who first helped themselves. In view, therefore, of the superior hygienic conditions, together with intelligent medical care, it is not surprising that seemingly marvellous cures should result, especially of impressionable persons affected with nervous disorders. The walls of those temples were adorned with bas-reliefs, of which specimens have been preserved. One of these represents a recumbent patient, and a physician seated by the bedside. Near by stands a tall, erect personage, supposed to be the god of health, while the figures of two suppliants may be seen approaching him.[98:1] When a patient arrived at the gate of the temple, he was not allowed to enter at once; for strict cleanliness was deemed a prerequisite for admission to the god's presence. And in order to place him in this desirable condition with the greatest possible despatch, he was plunged into cold water, after which he was permitted to enter the sacred precincts. According to a poetic fancy of the Grecian pilgrim in search of health, the proper cure for his ailment would be revealed by the god of healing to his worshipper in the latter's dreams.[98:2] The interpretation of these dreams and the revelation to the patient of their alleged meaning was entrusted to a priest, who served as an intermediary between Esculapius and the patient. Several of these oracular prescriptions, inscribed upon a marble slab, were found on the site of an Esculapian temple near Rome. Translations of two of them may serve as examples: "Lucius, having a pleurisy, and being given over by everybody, received from the god this oracle, that he should come and take the ashes off his altar, and mixing them with wine, apply them to his side. Which done, he was cured, and returned thanks to the god, and the people congratulated him upon his happy recovery." "The god gave this oracle to a blind soldier, named Valerius Aper, that he should mingle the blood of a white cock with honey, and make a collyrium, which he should put upon his eyes three days together. After which he saw, and came publicly to return thanks."[99:1]
