In the reign of Ancus Martius, King of Rome, a wealthy man, whose name was Tarquin, came to that city from one of the Etruscan States. Sitting beside his wife in his chariot, as he approached the gates of Rome, an eagle, it is said, plucked his cap from his head, flew up in the air, and then, returning, placed it on his head again. Not a few suspect that the eagle was a tame one and had been taught to perform this trick. If so, however, the apparent prodigy lost none of its effect in the popular belief, and Tarquin succeeded Ancus as King of Rome. The eagle's head on the Roman sceptre, and later on its standard, took its origin from this occurrence. Plutarch, in his life of Theseus, relates that when Cymon was sent by the Athenians to procure the bones of that hero, who had long before been buried in Scyros, to reinter them in his former capital, he found great difficulty in ascertaining the burial place of the ancient monarch. While prosecuting his search, however, he chanced to observe an eagle that had alighted on a small elevation and was trying with his beak and claws to break the sod. Considering this a fortunate omen, they explored the place and discovered the coffin of a man of extraordinary size, with a lance of brass and a sword lying by it. These relics were conveyed to Athens amid great rejoicing, where they found a resting place in the famous temple of Theseus, whose ruins are still in existence. The old historians state that the Greek poet Aeschylus lost his life through an eagle's mistaking his bald head for a rock and dropping a tortoise upon it in order to break the shell of his amphibious prey, but which broke, instead, the poet's skull. That an eagle, proverbially the keenest-sighted of created things, should mistake a man's head for a stone is absurd beyond the necessity of comment. The story is probably intended for an allegory, showing how stupidity can overwhelm genius, or a dull criticism smash a lively poet. In A. D. 431 there was war between the Emperor Theodosius II. and Genseric the Vandal, and Marcian, the general of the former, was taken prisoner. The unfortunate captive was doomed to death. At the place of execution an eagle alighted on his head and sat there some time undismayed by the tumult around it. Upon seeing this, and believing that the captive was destined for some exalted fortune, Genseric pardoned him and sent him home. About eighteen years afterwards Theodosius died, and, as his sister had married Marcian, the latter became Emperor of Constantinople.
