Quintus Antistius Adventus (c. 120 AD – after 175 AD) was a Roman politician and general. He commanded a legion, the II Adiutrix in the war against the Parthian Empire (161-166), and was appointed suffect consul around 166.[1]
His full name, as attested in two inscriptions from modern Algeria, was Quintus Antistius Adventus Postumius Aquilinus. Olli Salomies opines that his brother was Lucius Antistius Mundicius Burrus, and his nephew was likely Lucius Antistius Burrus, ordinary consul in 181. Where the name elements "Postumus Aquilinus" in Adventus' name came from is something of a mystery: Salomies points out that it is "quite inconceivable that he could have been a Postumus adopted by a Q. Antistius", yet notes it could have come from his mother's side because another inscription attests his mother's name as Antonia Prisca.[2]
