That Hippocrates was lineally descended from Æsculapius was generally admitted by his countrymen, and a genealogical table, professing to give a list of the names of his forefathers, up to Æsculapius, has been transmitted to us from remote antiquity. Although I am well aware that but little reliance can be put on these mythical genealogies, I will subjoin the list to this section, in order that it may be at hand for reference, as many allusions will have to be made to it in the subsequent pages.[22] Of the circumstances connected with the life of Hippocrates little is known for certain, the only biographies which we have of him being all of comparatively recent date, and of little authority. They are three in number, and bear the names of Soranus Ephesins, Suidas, and Tzetzes. Of the age in which the first of these authors flourished, nothing is known for certain; the second is a lexicographer, who lived in the beginning of the eleventh century; and the third flourished in the twelfth century. The birth of Hippocrates is generally fixed, upon the authority of Soranus, as having occurred in the first year of the 80th Olympiad, that is to say, in the 460th year before the vulgar era. On this point, however, I must say that I see no good grounds for the unanimity of opinion which has generally prevailed among modern scholars. In fact, the counter-evidence of Aulus Gellius has always appeared to me to be unjustly overlooked, as I cannot but think that his authority ought to rank much higher than that of Soranus, of whom nothing is known, not even the century in which he lived. Aulus Gellius, then, in an elaborate disquisition on Greek and Roman chronology, states decidedly that Socrates was contemporary with Hippocrates, but younger than he.[23] Now it is well ascertained, that the death of Socrates took place about the year 400 A.C., and as he was then nearly seventy years old, his birth must be dated as happening about the year 470 A.C. This statement would throw the birth of Hippocrates back several years beyond the common date, as given by Soranus. There is also much uncertainty as to the time of his death: according to one tradition he died at the age of 85, whereas others raise it to 90, 104, and even 109 years. These dates of his birth and death, although vague, are sufficient to show that the period at which we may reasonably suppose he had practised his profession with the greatest activity and reputation, must have been the latter part of the fifth century A.C. It will readily occur to the reader, then, that our author flourished at one of the most memorable epochs in the intellectual development of the human race. He had for his contemporaries, Pericles, the famous statesman; the poets Æschylus, Sophocles, Euripides, Aristophanes, and Pindar; the philosopher Socrates, with his distinguished disciples Plato and Xenophon; the venerable father of history, Herodotus, and his
