Lucius Valerius Messalla Thrasea Priscus[1] (died c. 212) was a Roman senator active during the reigns of Commodus and Septimius Severus.
[2] It is possible he was the son of Lucius Vipstanus Poplicola Messalla, who may have been a praetor designatus but died before he acceded to the consulate, by his wife Helvidia Priscilla.
[4] After stepping down from the consulate, Thrasea Priscus may have held the office of curator aquarum (or supervisor of aqueducts) in Rome, around 198.
[5] Thrasea Priscus may have been a partisan of Publius Septimius Geta, the brother and rival of the emperor Caracalla.
[6] Christian Settipani has speculated that Thrasea Priscus married Coelia Balbina, possibly the daughter of Marcus Aquilius Coelius Apollinaris, and a very close relative of the future Emperor Balbinus, due to the appearance of the cognomen Balbinus in his great-grandson's name.
