Aurelius Valerius Symmachus Tullianus (fl.
Writing between 334 and 337 (probably 337), the author Firmicus Maternus noted Tullianus for his austerity, severity, integrity, and Stoicism, though Cameron says this description represents an idealized image of a Roman senator and need not be an accurate depiction of the subject himself.
[2] Tullianus may be identical with one Phosphorius who served as proconsul of Achaia in 319.
'Phosphorius' occurs as an informal name (signum) elsewhere in his family and is otherwise rare, but confirmation of the identity is lacking.
[3][4] Tullianus' son was probably the senator Lucius Aurelius Avianius Symmachus.
