Bucephalus
亚历山大大帝最喜欢的马，来自希腊语 Boukephalos，字面意思是“牛头”，由 bous “牛”（来自 PIE 词根 *gwou- “公牛，母牛”）和 kephalē “头”（参见 cephalo-）组成。
Men called [him] Bucephalus ... of the marke or brand of a buls head, which was imprinted vpon his shoulder. [Pliny, I.220, tr. Holland, 1601]
人们称他为布塞法罗斯……因为他肩上印有一个公牛头的标记或烙印。[普林尼，I.220，汉兰达译，1601年]
