Answer the following question: What was the original name of the structure that Titus inaugurated the completion of?  Answer the above question based on the context below:  The inaugural games were held, on the orders of the Roman Emperor Titus, to celebrate the completion in AD 80 (81 according to some sources) of the Colosseum, then known as the Flavian Amphitheatre (Latin: Amphitheatrum Flavium). Vespasian began construction of the amphitheatre around AD 70 and it was completed by his son Titus who became emperor following Vespasian's death in AD 79. Titus' reign began with months of disasters – including the eruption of Mount Vesuvius, a fire in Rome, and an outbreak of plague – he inaugurated the completion of the structure with lavish games that lasted for more than one hundred days, perhaps in an attempt to appease the Roman public and the gods. Little literary evidence survives of the activities of the gladiatorial training and fighting (ludi). They appear to have followed the standard format of the Roman games: animal entertainments in the morning session, followed by the executions of criminals around midday, with the afternoon session reserved for gladiatorial combats and recreations of famous battles. The animal entertainments, which featured creatures from throughout the Roman Empire, included extravagant hunts and fights between different species. Animals also played a role in some executions which were staged as recreations of myths and historical events. Naval battles formed part of the spectacles but whether these took place in the amphitheatre or on a lake that had been specially constructed by Augustus is a topic of debate among historians. Only three contemporary or near-contemporary accounts of the games survive. The works of Suetonius and Cassius Dio focus on major events, while Martial provides some fragments of information on individual entertainments and the only detailed record of a gladiatorial combat in the arena known to survive: the fight between Verus and Priscus.
