Baʹyard.

A horse of incredible swiftness, belonging to the four sons of Ayʹmon. If only one of the sons mounted, the horse was of the ordinary size; but if all four mounted, his body became elongated to the requisite length. The name is used for any valuable or wonderful horse, and means a “high-bay” (bay-ard). (Villeneuve: Les Quatre-Filz Aymon.) (See Horse.)
