Variations: Cricos, Crichos
The story of the Circhos is one fraught with misunderstandings, mistranslations, and general confusion. It should serve as a morality tale on the importance of accurate information transmission.
Aristotle describes the habits of hermit crabs in detail. The carcinium (“small crab”) is soft-bodied after the thorax, resembling a spider, with two red horns and forward-pointing eyes. The mouth has hair-like appendages and two divided feet that it uses to catch prey. There are two additional smaller pairs of feet beside them.
Of the hermit crabs, the kind that lives in the nerita or brita shell is unusual because its right divided foot is small while the left one is large. It walks more on the left foot than the right. The nerita itself, Aristotle adds, has a large, smooth, rounded shell, and a red hepatopancreas, as opposed to the ceryx and its black hepatopancreas. During a storm the crabs hide under a rock, and the gastropods attach themselves to the rock and close their opercula.
All of the preceding information is stated consecutively. Michael Scot’s translation of Aristotle gives the name of kiroket to the nerita shell. Thomas de Cantimpré takes Scot’s kiroket and his descriptions of the hermit crab and gastropod, but omits connecting names and details to combine them into a single confused account. It is likely that Scot’s jargon and neologisms threw Thomas off.
Thomas de Cantimpré’s cricos (corrupted from kiroket) now has two fissures at the end of its feet, giving it three fingers and three nails on each foot (Thomas’ “common-sense” addition). Its left foot is big and its right foot is small, and it carries its weight on its left foot. The comparison of hepatopancreas colors becomes the shell of the cricos, colored black and red. In good weather, the cricos moves around; in bad weather, it attaches itself to rocks and doesn’t move.
Albertus Magnus takes up Thomas’ account, but drops the confusing details of the feet. The Ortus Sanitatis, on the other hand, creates some additional features out of whole cloth. The circhos or crichos has the head of a man and the body of a sea-dog (i.e. a dogfish or shark); it is healthy in good weather, but weakens and turns ill in bad weather.
Olaus Magnus borrows the circhos of the Ortus Sanitatis to populate his Scandinavian sea. The physical description of a human-headed fish is wisely redacted. Whether it was meant to represent an actual Scandinavian animal, or is merely plagiarism, remains unclear.
It is Olaus Magnus’ account that is best known today. Concept drift in modern retellings have led to fabrications such as a limping gait that forces the circhos to move only in fine weather and cling to rocks during storms, and even a “humanoid” appearance.
