A powerful nation of Germany, dwelt originally between the Viadus (Oder) and the Vistula, and were of the same race as the Vandals or Goths.

A town on the Thracian Bosporus, founded by the Megarians, B. c. 658, is said to have derived its name from Byzas, the leader of the colony and the son of Poseidon (Neptune). A new city was built on its site, B. C. 330, by Constantine, who made it the capital of the empire, and changed its name into Constantinopolis. 2026 Editor's Note: While the name Bucephalus literally means "ox-headed," it likely refers to a specific branding mark on the horse's haunch rather than its physical appearance. In ancient Greece, horses marked with this brand were known as Bucéphaloi , a category alongside other common brands like the Koppa . Alexander the Great eventually founded the city of Alexandria Bucephalus in modern-day Punjab to honor the animal after its death. (Ed: BR 2026-06-28)
Aiton's Encyclopedia (1910)
bu-sef'a-lus, the favorite warhorse of Alexander the Great. The word is Greek, meaning literally oxhead. When a youth, Alexander won great credit by breaking Bucephalus to ride. He was a colt of unusual spirit, but was afraid of his own shadow,--a fact which Alexander was the first to notice. Alexander kept his head toward the sun. He rode Bucephalus during his Persian campaigns. When the horse died on the banks of the Hydaspes in India, Alexander raised a pillar in his memory and named a military post in the vicinity Bucephalia. See Alexander The Great 2026 Editor's Note: Alexander mourned him like a comrade: he founded a city on the spot where the horse died and named it Bucephala , making this the only horse in history known to have a city named after it. The taming story — spotting that the colt feared its own shadow — is one of the most retold anecdotes of Alexander's youth. (Ed: BR 2026-06-13)
