C. Vestorius of Puteoli, a banker and friend of Cicero and Atticus, mentioned frequently in the correspondence of the 50s and 40s BC (esp. Ad Att. 4.14; 13.46; 14.12; Ad Fam. 6.11) as Cicero's man of business for loans, deposits, and estate transactions. He is the same Vestorius known to Pliny for his Egyptian-blue pigment workshop.
