The biga (Latin; pl.: bigae) is the two-horse chariot as used in ancient Rome for sport, transportation, and ceremonies. Other animals may replace horses in art and occasionally for actual ceremonies. The term biga is also used by modern scholars for the similar chariots of other Indo-European cultures, particularly the two-horse chariot of the ancient Greeks and Celts. The driver of a biga is a bigarius.[1]
Other Latin words that distinguish chariots by the number of animals yoked as a team are quadriga, a four-horse chariot used for racing and associated with the Roman triumph; triga, or three-horse chariot, probably driven for ceremonies more often than racing (see Trigarium); and seiugis or seiuga, the six-horse chariot, more rarely raced and requiring a high degree of skill from the driver. The biga and quadriga are the most common types.
Two-horse chariots are a common icon on Roman coins; see bigatus, a type of denarius so called because it depicted a biga.[2] In the iconography of religion and cosmology, the biga represents the moon, as the quadriga does the sun.[3]
