The Pompeian banker Caecilius was born around the end of Augustus's reign (c. 15 AD) to a freedman named Felix, who was also a banker. By 58 AD he was well-established as a successful banker who dealt with a wide variety of Pompeians. Freedmen and slaves performed many small business tasks for Iucundus, such as signing receipts as witnesses and collecting payments from clients. Many names of elite Pompeian citizens occur frequently in his transaction records, suggesting that Caecilius also had dealings with the upper class of his town. In fact, he even traveled to nearby Nuceria to help the wealthy Praetorian Guard senior centurion Publius Alfenus Varus resell some slaves that he had purchased in an auction.
