Gaius Suetonius Tranquillus, Tib.  15.1  (ca. A.D. 98-117):

Romam reversus deducto in Forum filio Druso statim e Carinis ac Pompeiana domo Esquilias in hortos Maecenatianos transmigravit totumque se ad quietem contulit, privata modo officia obiens ac publicorum munerum expers.

On his return to Rome, after introducing his son Drusus to public life, he [Tiberius] at once moved from the Carinae and the house of the Pompeius' to the gardens of Maecenas on the Esquiline, where he led a very retired life, merely attending to his personal affairs and exercising no public functions.
