in the earlier part of the reign of Tiberius had been praetor, but in what year is unknown.
He was a creature of Sejanus, and aspired to the consulship.
But at that time elation was the readiest road to preferment. Titius Sabinus had offended Sejanus by his steady friendship to the widow and children of Germanicus. Him, therefore, in A. D. 28, Latiaris singled out as his victim and stepping-stone to the consular fasces.
He wormed himself into the confidence of Sabinus, and encouraged him to speak of Agrippina's wrongs and Sejanus' tyranny in a room where three confederates lay hid between the ceiling and the roof.
After the fall of Sejanus, Latiaris was soon marked for destruction by Tiberius.
The senate gladly condemned him, and Latiaris died without a murmur in his favour. (Tac. Ann. 4.68
