- EACH UISCE or EACH UISGE (the Highland water horse, pronounced something like ech-ooshkya)
- AUGHISKY or AUGHISKA (same as the Highland water horse, known in Ireland, pronounced something like agh-iski)
- Related is Cabyll Ushtey, which literally translated, means something like fish horse
Notice the connection between the word mare (from Latin mare-sea), which also means horse/mare (mare = a female horse, the LL 'caballus' = male horse) in English, march in Welsh (female horse) -- "King Mark" (a/k/a "March") in the tale "Tristan and Isolde:" The king's name - March, may have meant "ass' ears", which explained why the latter legend says that he had the ears of horse or ass.
And then there is the cabyll ushtey - the fish horse - possibly so named because of the resemblance of the spiny "ruff" that runs down the middle of the head/back of such species of fish to a horse's mane. "Cabyll" might be from L caballus, a gentleman trained in arms and horsemanship, a mounted soldier: knight. However, it also might be from "cavalla" : Sp (Spanish) caballa, a fish, fr. LL., mare, fem. of L caballus) 1. CERO 2. also ca-val-ly: any of various carangid fishes (esp. genus Caranx). From Webster's Collegiate:
Cero: n. pl. cero or ceros [modif. of Sp sierra saw, cero]: either of two large food and sport fishes (Scomberomorus cavalla and S. regalis) of the warmer parts of the western Atlantic ocean. Caranx (no definition found); Carangid: adj [deriv. of F carangue shad, horse mackerel, fr. Sp caranga]:of or relating to a large family (Carangidae) of marine spiny-finned fishes including important food fishes - carangid n.
So - where am I going with all of this, you ask. Well - here's the reach. I've been fascinated for years by chess historian Pavel Bidev's description of the knight's move in chess as being related to water and that it traces out the shape of the crescent Moon. (Transcribed article at Goddesschess) As we know, the Moon is anciently and intimately related to various goddesses who are also connected to the sea and, of course, there is the well known effect of the Moon's phases upon the tides. Thus, my research into - literally - water horses.
Someday I'll put all of this research together into a coherent (I hope) article and relate it to the history of the chess piece we call the knight.
