Cic. Fam. 13.29: “…I am exceedingly intimate with C. Ateius Capito. You know what the ups and downs of my fortunes have been. In every position of honour or of difficulty of mine, Capito’s courage, active assistance, influence, and even money were ever at my service, supplied my occasions, and were ready for every crisis. He had a relation named Titus Antistius. While this man was serving in Macedonia as quaestor, according to the lot, and had had no successor appointed, Pompey arrived in that province at the head of an army. Antistius could do nothing. For if he had had things his own way, there is nothing he would have preferred to going back to Capito, for whom he had a filial affection, especially as he knew how much he valued Caesar and had always done so. But, being taken by surprise, he only engaged in the business as far as he was unable to refuse. When money was being Coined at Apollonia, I cannot say that he presided at the mint, nor can I deny that he was engaged in it; but it was not for more than two or three months. After that he held aloof from the camp: he avoided official employment of every sort. I would have you believe me on this point as an eye-witness: for he used to see my melancholy during that campaign, he used to talk things over with me without reserve. Accordingly, he withdrew into hiding in central Macedonia at as great a distance as he could from the camp, so as to avoid not only taking command in any department, but even being on the spot.
Crawford (RRC vol. 1 p. 80) of course knows this, but still exciting to read a fresh in Cicero.
I want to think more about how he might connect to later Anstitii who serve as moneyers.
