Quadrigatus

Quadrigatus is the name for a Roman silver coin dating from the 3rd century BC worth 2 drachmas with the appearance of a four-horse horse carts. Accordingly, three - and two-horse as Trigatus or Biga ( tus ) are called. On the back is the representation of a moving to the right Quadriga with the lightning flinging God the Father Jupiter and the goddess Victoria. The front features the famous Janus head. According to another estimate, it could also be the Dioscuri Castor and Pollux. The 6.8 g of vast coin was minted around 241-235 BC.

There was also a half Quadrigatus with Janus head worth one drachma, where the Quadriga moves to the left. It can - in addition to the eigenständischen Sicilian- Southern Italian drachmas ( - LITRA ) currency - be regarded as a forerunner of from about 211 BC marked denarius.

At the same time, similar pieces of gold with a value of one or half a stater minted.
