Marcus Junius Homullus was a Roman senator active in the late 1st and early 2nd centuries AD, who occupied a number of offices in the imperial service.
Bernard Rémy notes that his cognomen, "Homullus", appears primarily in Italy, so this may be where his origins lie.
In the first, Pliny mentions that Homullus and Tiberius Catius Caesius Fronto defended Julius Bassus against charges of malfeasance while governor of Bithynia and Pontus.
"[8] McDermott believes this anecdote was drawn from the hypothetical source for the Historia Augusta, the history of Marius Maximus.
"Such an eastern campaign must have been considered a dubious exploit, or even disastrous, by many of the members of the senate, even though it only gradually became evident how far the emperor would go," McDermott writes.
