And Philyllius, or Eunicus, or Aristophanes, in the Cities, says-- A little polypus, or a small cuttle-fish, A crab, a crawfish, oysters, cockles, Limpets and solens, mussels and pinnas; Periwinkles too, from Mitylene take; Let us have two sprats, and mullet, ling, And conger-eel, and perch, and black fish. But Agiastos, and Dercylus, in his Argolici, call the strabeli ἀστράβηλοι; speaking of them as suitable to play upon like a trumpet. 33. But you may find cockles spoken of both in the masculine and feminine gender. Aristophanes says, in his Babylonians-- They all gaped on each other, and were like To cockles (κόγχαι) roasted on the coals. And Teleclides, in his Hesiodi, says, "Open a cockle (κόγχη);" and Sophron, in his Actresses, says-- And then the cockles (κόγχαι) as at one command All yawned on us, and each display'd its flesh. But Æschylus uses the word κόγχος in the masculine gender, in his Glaucus Pontius, and says-- Cockles (κόγχοι), muscles, oysters. And Aristonymus, in his Theseus, says-- There was a cockle (κόγχαι) and other fish too drawn from the sea At the same time, and by the same net. And Phrynichus uses the word in the same way in his Satyrs. But Icesius, the Erasistratean, says that some cockles are rough, and some royal; and that the rough have a disagreeable juice, and afford but little nourishment, and are easily digested; and that people who are hunting for the purple-fish use them as bait: but of the smooth ones those are best which are the largest, in exact proportion to their size. And Hegesander, in his Memorials, says that the rough cockles are called by the Macedonians coryci, but by the Athenians crii. 34. Now Icesius says that limpets are more digestible than those shell-fish which have been already mentioned; but that oysters are not so nutritious as limpets, and are filling, but nevertheless are more digestible.
