Who is Titus from The Twelve Caesars and what is their importance?

Titus is the better of Vespasian's sons. He is loved by all the people and is generally a good leader, though it takes the public a while to accept him. He does a lot of good and is very honest and respectable towards the public. His brother hates him however and is always plotting against him. Titus sees major catastrophes during his reign, including a volcano eruption, a horrible plague, and a fire that lasts three days and nights.
