Lucius Antistius Vetus (died AD 65) was a Roman senator who lived during the Principate.
Immediately after his consulate, Vetus was appointed governor of Germania Superior, where he attempted construction of a canal that would join the Rhine and Rhone rivers and facilitate traffic.
Tacitus claims it was because he was the father-in-law of Rubellius Plautus, whom Nero had executed several years before,[4] although Vetus was also accused of wrongdoing by his freedman Fortunatus and Claudius Demianus; Nero had released Demianus in return for his accusations against Vetus.
[5] After Vetus retired to his estate at Formiae, his daughter Politta sought to plead his case before the emperor, but as she was forbidden to approach him, according to Tacitus "she would haunt his doors and implore him to hear an innocent man."
Vetus then manumitted his slaves, giving them all his ready money and ordered each to take of his possessions whatever they could carry, and with his daughter and mother-in-law Sextia, the three committed suicide.
