Almost every important gallery of sculpture in Europe possesses at least one marble statue of Aesculapius, and in the majority of these the god is represented as a middle-aged or elderly man of powerful frame, having a full head of hair and full beard, and clothed only with the pallium or mantle, which is so placed as to leave the right shoulder and a large part of the chest uncovered. He holds in his right hand a knotted staff around which, in many of the statues, is coiled a serpent whose head approaches very closely to the hand. The expression of the god’s countenance is strikingly peaceful and serene, yet without any evidence of weakness. In not a few instances other animals are represented alongside the statue, usually at the god’s feet--as, for example, the cock, the owl, the eagle, the hawk or the ram--and occasionally his daughter Hygieia is shown at his side feeding the serpent. The cock is the symbol of watchfulness--a physician should be vigilant; the owl symbolizes his need of clear-sightedness and of readiness to care for his patients in the night as well as during the day; the eagle has a penetrating eye and it is the emblem of long life--a benefit which the healing art is capable of procuring; the hawk was the bird consecrated to Isis, Queen of Egypt, who was believed by the Egyptians to have been highly skilled in medicine; and the ram is the symbol of dreams and divination. Pliny says that the patients who were brought to the temple of Aesculapius were made to lie down at night wrapped in the skin of a ram, in order that they might have divine dreams. The presence of the serpent in nearly all of the statues of Aesculapius is explained in a variety of ways. Some say that this reptile, which sheds his skin once a year, is emblematic of the sick person’s need to acquire a new body, or at least cast off his old skin in the same manner as does the snake. Others consider the serpent as merely the symbol of wisdom, as it is admittedly the shrewdest and most cunning of all animals. In a few instances it is represented as drinking from a receptacle held in the hand of Hygieia. Perhaps the sculptor’s intention here was to show that the serpent, although the wisest of all animals, believed that he might add to his stock of wisdom by drinking from the fountain under the control of Aesculapius, thus conveying the impression that the wisdom of the latter was greater than his own. But all these interpretations are too subtle for the uneducated mind to appreciate at a glance. They fail also to satisfy our preconceived ideas of what such a statue should be--viz., a memorial of the godlike character of Aesculapius and of the priceless benefits which he conferred upon his fellow men, and, at the same time, an object which, when first contemplated by one who is ill, would at once evoke in that person feelings of perfect confidence in the ability and the willingness of the god represented by the statue to effect a cure.
