The fish of Phoenicia, excepting certain shell-fish, are little known, and have seldom attracted the attention of travellers. The Mediterranean, however, where it washes the Phoenician coast, can furnish excellent mullet,[283] while most of the rivers contain freshwater fish of several kinds, as the Blennius lupulus, the Scaphiodon capoeta, and the Anguilla microptera.[284] All of these fish may be eaten, but the quality is inferior.
On the other hand, to certain of the shell-fish of Phoenicia a great celebrity attaches. The purple dye which gave to the textile fabrics of the Phoenicians a world-wide reputation was prepared from certain shell-fish which abounded upon their coast. Four existing species have been regarded as more or less employed in the manufacture, and it seems to be certain, at any rate, that the Phoenicians derived the dye from more shell-fish than one. The four are the Buccinum lapillus of Pliny,[285] which is the Purpura lapillus of modern naturalists; the Murex trunculus; the Murex brandaris; and the Helix ianthina. The Buccinum derives its name from the form of the shell, which has a wide mouth, like that of a trumpet, and which after one or two twists terminates in a pointed head.[286] The Murex trunculus has the same general form as the Buccinum; but the shell is more rough and spinous, being armed with a number of long thin projections which terminate in a sharp point.[287] The Murex brandaris is a closely allied species, and “one of the most plentiful on the Phoenician coast."[288] It is unlikely that the ancients regarded it as a different shell from Murex trunculus. The Helix ianthina has a wholly different character. It is a sort of sea-snail, as the name helix implies, is perfectly smooth, “very delicate and fragile, and not more than about three-quarters of an inch in diameter."[289] All these shell-fish contain a sac or bag full of colouring matter, which is capable of being used as a dye. It is quite possible that they were all, more or less, made use of by the Phoenician dyers; but the evidence furnished by existing remains on the Tyrian coast is strongly in favour of the Murex brandaris as the species principally employed.[290]
