Could it be camelopard or camelion, a mythical composite creature? although the earliest OED citation of either is as late as 1382. The Afrikaans word for giraffe, kameelperd, led me to this:
“The Egyptians used a hieroglyph in the shape of a giraffe to indicate ‘to prophecy’, ‘to foretell’, which has been taken as evidence of its keen eyesight. Ancient Arabic words include saraphah, gyrapha, gyraffa, and zirafa. The Persians called it ushturgao ("camel-cow"). To the Chaldeans it was deba, and ana, which may be related to nabun, used by Pliny. The encyclopedist Vincent de Beauvais, in his Speculum Naturale (1225), described it under three different names (anabulla, camelopardo, and orasius), apparently without realizing it. Albertus Magnus repeated the mistake in his thirteenth-century De Animalibus, using anabula, camelopardulus, and oraflus. Anabula probably comes from the Ethiopians, who called it nabin; and orafle was used in Old French. In Afrikaans it is called kameelperd. and in Zulu indlulamethi. But my personal favorite is the Swahili word twiga—which sounds the way a giraffe looks. [Tall Blondes, Lynn Sherr, p.19.]
The giraffe in heraldry is known as
Camelopardel: the camelopard, or giraffe, with two long horns slightly curved backward, used only as a crest.
More on heraldry:
The medieval name for an ordinary giraffe was camelopard. It was a widely believed at that time that animals sometimes crossbred. It is likely that a crusader saw a giraffe for the first time and believed it to be a cross between a camel and a leopard. It is believed that the camelopard represented characteristics of both “parents”, namely a valiant warrior that would patiently persevere to the end.
