Eurybiades, by reason of the greatness of Sparta, was admiral of the Greek fleet, but yet was faint-hearted in time of danger, and willing to weigh anchor and set sail for the isthmus of Corinth, near which the land army lay encamped; which Themistocles resisted; and this was the occasion of the well-known words, when Eurybiades, to check his impatience, told him that at the Olympic games they that start up before the rest are lashed; "And they," replied Themistocles, "that are left behind are not crowned." Again, Eurybiades lifting up his staff as if he were going to strike, Themistocles said, "Strike if you will, but hear;" Eurybiades, wondering much at his moderation, desired him to speak, and Themistocles now brought him to a better understanding. And when one who stood by him told him that it did not become those who had neither city nor house to lose, to persuade others to relinquish their habitations and forsake their countries, Themistocles gave this reply: "We have indeed left our houses and our walls, base fellow, not thinking it fit to become slaves for the sake of things that have no life nor soul; and yet our city is the greatest of all Greece, consisting of two hundred galleys, which are here to defend you, if you please; but if you run away and betray us, as you did once before, the Greeks shall soon hear news of the Athenians possessing as fair a country, and as large and free a city, as that they have lost." These expressions of Themistocles made Eurybiades suspect that if he retreated the Athenians would fall off from him. When one of Eretria began to oppose him, he said, "Have you anything to say of war, that are like an ink-fish? you have a sword, but no heart." Some say that while Themistocles was thus speaking things upon the deck, an owl was seen flying to the right hand of the fleet, which came and sat upon the top of the mast; and this happy omen so far disposed the Greeks to follow his advice, that they presently prepared to fight. Yet, when the enemy's fleet was arrived at the haven of Phalerum, upon the coast of Attica, and with the number of their ships concealed all the shore, and when they saw the king himself in person come down with his land army to the seaside, with all his forces united, then the good counsel of Themistocles was soon forgotten, and the Peloponnesians cast their eyes again towards the isthmus, and took it very ill if any one spoke against their returning home; and, resolving to depart that night, the pilots had order what course to steer. The Teuthis, loligo, or cuttlefish, is said to have a bone or cartilage shaped like a sword, and was conceived to have no heart.
