Cicero to Atticus, written from the Tusculanum on the fourth day before the Nones of June 709 AUC — 2 June 45 BC (the manuscript dateline: Scr.\ in Tusculano iv Non.\ Iun.\ a.\ 709 (45)). The note picks up the antiquarian thread of the previous day’s letter and at once corrects it. Cicero had named Sp. Mummius among the ten legates sent out after the destruction of Corinth in 146; on reflection the legate must have been his brother Lucius, the conqueror himself. The single Greek word eulogon — the Stoic term of art for what “stands to reason” — is the wry self-mark of a philosopher catching his own slip.

The rest of the section is house-keeping for two parallel transactions. “I have sent you the Torquatus” is a presentation copy of the dialogue that will become Book 1 of the De Finibus, with L.~Manlius Torquatus as the Epicurean spokesman. The pressing of Silius concerns the long-running attempt to acquire suitable horti on the Tiber for the shrine to Tullia; “that day” and “this one” are two possible closing dates which only Atticus, who has been doing the negotiating in town, can keep straight. Crispus and Mustela are further owners in the same property dance. The closing thanks acknowledge what these letters everywhere acknowledge — that Atticus’s June is being spent on Cicero’s affairs.
