|[C14: from Old French cocatris, from Medieval Latin cocatrix, from Late Latin calcātrix trampler, tracker (translating Greek ikhneumon|
the mediaeval name (a corruption of "crocodile") of a fabulous serpent supposed to be produced from a cock's egg. It is generally supposed to denote the cerastes, or "horned viper," a very poisonous serpent about a foot long. Others think it to be the yellow viper (Daboia xanthina), one of the most dangerous vipers, from its size and its nocturnal habits (Isa. 11:8; 14:29; 59:5; Jer. 8:17; in all which the Revised Version renders the Hebrew _tziph'oni_ by "basilisk"). In Prov. 23:32 the Hebrew _tzeph'a_ is rendered both in the Authorized Version and the Revised Version by "adder;" margin of Revised Version "basilisk," and of Authorized Version "cockatrice."
in the legends of Hellenistic and Roman times, a small serpent, possibly the Egyptian cobra, known as a basilikos ("kinglet") and credited with powers of destroying all animal and vegetable life by its mere look or breath. Only the weasel, which secreted a venom deadly to the cockatrice, was safe from its powers
