Short answers, pulled from the story.
The Temple of Divus Augustus rose between the Palatine and Capitoline Hills, standing behind the Basilica Julia. It occupied the site of a house where Augustus had lived before entering public life in the mid-1st century BC.
Roman Senate vows for this temple came shortly after the emperor died in AD 14. Completion did not arrive until after Tiberius passed away in 37 AD when his successor Caligula finally dedicated the finished structure.
Caligula ordered exceptional festivities during the last two days of August 37 to dedicate the finished structure. The climax occurred on Caligula's birthday and the final day of his consulship to emphasize him as Augustus' direct descendant.
Domitian's reign saw the original Temple of Divus Augustus destroyed by fire. Rebuilding efforts concluded around 89 or 90 AD with a shrine added for Minerva.
Cassius Dio recorded that horse races ran along with the slaughter of 400 bears during the festivities. An equal number of wild beasts from Libya also perished during these events.
