The Colosseum or Coliseum, originally capable of seating 45,000 - 50,000 spectators, it was used for gladiatorial contests and public spectacles. It was built on a site just east of the Roman Forum, with construction starting between 70 and 72 AD under the emperor Vespasian. The amphitheatre, the largest ever built in the Roman Empire, was completed in 80 AD under Titus, with further modifications being made during Domitian's reign.
In the period of rule of Emperor Trajan is said to have celebrated his victories in Dacia in 107 with contests involving 11,000 animals and 10,000 gladiators over the course of 123 days.
Ave Caesar! Morituri te Salutant!, translates as “Hail, Caesar, those who are about to die salute you«. That is traditionally the Latin phrase that the gladiators addressed to the emperor before the beginning of a gladiatorial match. Vespasian is known by another Latin proverb - "Pecunia non olet" which means "Money does not smell"; and it is said that it has been created when he had introduced a urine tax on public toilets.
