A relatively obscure historical figure, Quintus Caecilius Iucundus is most notable as a major character in the Cambridge Latin Course, set in the Ancient Roman Empire.
In the first volume of the Cambridge Latin Course, the reader finds Quintus as a teenager in Pompeii, in AD 78, the year before it is destroyed by Mount Vesuvius.
When Barbillus died, he tasks Quintus to find his estranged son and heir, Rufus, in Britain.
[4] It is possible that Quintus held the cognomen Metellus, as did his brother, apparently granted by their father to suggest a connection with the prestigious Caecilii Metelli.
[4] Since Caecilius' banking business appears to have been abandoned on his likely death in AD 62, it is considered likely that Quintus and Sextus did not follow their father into the profession.
