The oldest testimony of chariot warfare in the ancient Near East is the Old Hittite Anitta text (18th century BC), which mentions 40 teams of horses (in the original cuneiform spelling: 40 "ṢÍ-IM-TI" ANŠE.KUR.RAḪI.A) at the siege of Salatiwara. Since the text mentions "teams" rather than "chariots", the existence of chariots in the 18th century BC is uncertain. The first certain attestation of chariots in the Hittite empire dates to the late 17th century BC (Hattusili I). A Hittite horse-training text is attributed to Kikkuli the Mitanni (15th century BC).
