One of the most profitable of the Greek fisheries was that of the thunny, which commenced about the rising of the Pleiades and terminated shortly after the setting of Arcturus.[1439] As this animal always moves about in troops, and swims near the surface of the water, which it visibly disturbs in its progress, at the same time blowing sportively, and uttering a loud noise, the fishermen, on the shores frequented by it, constantly stationed a number of watchmen along the beach, some perched aloft on the summits of cliffs, others on detached rocks, rising out of the waves, or in trees, or on the top of masts set up at certain distances along the coast, that they might give notice of the approach of the thunnies.[1440] As soon as the signal was given the fishermen pushed out with their barks, making a wide circuit, so as to take the fish in flank. Then letting down their long nets furnished with leaden weights to sink them, and with cords[1441] wherewith to draw them up, they formed themselves into a semicircle, which rapidly narrowing round the shoal drove them towards the land, by which means the greatest number were either taken in the nets, or speared by tridents.[1442] Respecting one of these fishing stations, on the coast of Cypros, a very romantic anecdote is related.[1443] The inhabitants we are told, having sculptured a marble lion, which they adorned with emerald eyes, set it up on the tomb of a prince of the country named Hermias,[1444] upon an eminence overlooking the sea. The splendour of the emerald, penetrating through the waves, scared away the thunnies, which in truth are remarkable for their timidity, so that the fishermen of that part of the island must unquestionably have been ruined had they not discovered the property of their lion’s optics, and substituted in lieu of the emerald, eyes less terrible to the pusillanimous herds of Thetis. A circumstance almost equally extraordinary is related of the strait by which the stream of the Bosporos disgorges itself into the Propontis. Here they say a rock of marvellous whiteness is discovered on the Asiatic side through the waves in the neighbourhood of Chalcedon, which by its brightness scares away the thunnies, both in their way to and from the Black Sea. The ancient naturalists remark, that the thunny in this part of its migrations observes steadily one course, keeping generally on the Asiatic side in the ascent to the Pontus, where, excepting the seal and the dolphin, nothing destructive to fish is found, and, after making the circuit of its shores, returning to the Ægæan close along the coast of Europe. ----- Footnote 1439: Plin. ix. 20.
