The priests of Aesculapius possessed a never failing source of information on the recipes or votive tablets with which these temples abounded. These were sometimes engraven on pillars, as at Epidaurus; of which Pausanias says there were six remaining in his time, and besides these, one in particular removed from the rest, on which it was recorded that Hippolytus had sacrificed twenty horses, in return for his having been restored to life by him. Five memorials only of this kind have reached the present age. One of them is to be found in the beginning of Galen's fifth book de Compos, medic.: it is taken from the temple of Phthas, near Memphis, and is the least interesting of the whole. Its subject is the use of the Diktamnus, borrowed from Heras of Cappadocia, a medical writer, frequently quoted by Galen. The remaining four are much more important: they were engraven on a marble slab,[108] of later date at Rome, and are thought, with much probability, to have belonged to the Aesculapian temple in the Insula Tiberina. The present translation, in which some errors either of the artist or copyist are rectified, is extracted from the first volume of Gruter's Corp. Inscriptionum. The narrations are perspicuous and laconic. 1. "In these latter days, a certain blind man, by name Caius, had this oracle vouchsafed to him--'that he should draw near to the altar after the manner of one who could see; then walk from right to left, lay the five fingers of his right hand on the altar, then raise up his hand and place it on his eyes.' And behold! the multitude saw the blind man open his eyes, and they rejoiced, such splendid miracles should signalize the reign of our Emperor Antoninus." 2. "To Lucius, who was so wasted away by pains in his side, that all doubted of his recovery, the god gave this response: 'Approach thou the altar; take ashes from it, mix them up with wine and then lay thyself on thy sore side.' And the man recovered, and openly returned thanks to the god amidst the congratulations of the people." 3. "To Julian who spitted blood, and was given over by every one, the god granted this response: 'Draw near, take pine apples from off the altar, and eat them with wine for three days. And the man got well, and came and gave thanks in the presence of the people." 4. "A blind soldier, Valerius Asper by name, received this answer from the god: that he should mix the blood of a white cock with milk, make an eye ointment therewith, and rub his eyes with it for three days. And lo! the blind recovered his sight, and came, and publicly gave thanks to the god."
