He spoke with ease in both Latin and Greek, in an elegant and ornate style.
Charles Thomas Cruttwell says that Arellius was an Asiatic, that is, a practitioner of an elevated oratorical style.
He was probably the teacher of Ovid (43 BC – 17/18 AD)[1] and Pliny the Elder (23–79).
He is mentioned in the Naturalis Historia of the latter.
Another pupil was Papirius Fabianus.
