Variations: Chargol, Ophiomachis, Ophiomachus, Opimacus, Opymachus, Ibis, Snake-eater; Attachus (probably); Opinicus, Epimacus (probably)
There is only one Biblical mention of the insect called chargol, in Leviticus 11:22, as one of the four insects that are safe for consumption. It has been assumed to mean “beetle” in some translations. Other identifications include a katydid or bush cricket, a species of Gryllus cricket, or the wart-eating cricket.
The Septuagint’s translators borrowed heavily from Aristotle in an effort to give names to all the animals in the Bible. An Aristotelian account of locusts fighting and killing snakes (perhaps based on stories of insects feeding on dead snakes?) gave the chargol the name of ophiomachus, “snake fighter”. This in turn became the opimachus or opimacus, described by Thomas de Cantimpré and subsequently Albertus Magnus as a worm that attaches itself just below a snake’s head. It cannot be removed and kills the snake.
By the time the opimachus or opymachus was described in the Ortus Sanitatis (citing Thomas), it had become confused beyond recognition. While Thomas and Albertus list it among the insects, it is now placed with the birds as a small fowl. It is depicted as a quadrupedal griffin with a long pointed beak and large rabbit’s ears. It has longer hind legs to permit it to jump. It may or may not be the same as the bird known as attachus.
Dapper says that the ophiomachi or ibides (ibises) are birds that live in Ethiopia and are so named because they eat snakes.
Finally, the long journey of the snake-fighter comes to an end with the opinicus or epimacus, a variety of generic heraldic griffin whose name is almost certainly derived from a Levitical insect.
