Athaulf declaration. Medical background It is not unreasonable but also not necessary to conclude that Marcellus was a practicing physician. In his dissertation, the intellectual historian of magic and medicine Lynn Thorndike pronounced him the “court physician” of Theodosius I, but the evidence is thin: Libanius, if referring to this Marcellus, praises his ability to cure a headache. The prevailing view is that Marcellus should be categorized as a medical writer and not a physician. A translator of the medical writings of Isidore of Seville characterizes Marcellus as a “medical amateur” and dismisses the De medicamentis as “nothing more than the usual ancient home remedies,” and the historian of botany Ernst Meyer seems to have considered him a dilettante. Like Ausonius and later Sidonius Apollinaris, Marcellus is among those aristocratic Gauls of the 4th and 5th centuries who were nominally or even devoutly Christian but who fashioned themselves after the Republican ideal of the Roman noble: a career in politics balanced with country villas and informational or literary writing on a range of subjects, including philosophy, astronomy, agriculture, and the natural sciences. Although medical writing might have been regarded as a lesser achievement, it was a resource for the pater familias who traditionally took personal responsibility for the health care of his household, both family members and slaves. Prescriptions for veterinary treatments dispersed throughout the De medicamentis also suggest the interests and concerns of the author — the letter from Symmachus serves mainly to inquire whether Marcellus can provide thoroughbred horses for games to be sponsored by his son, who has been elected praetor — and of his intended audience, either the owners of estates or the literate workers who managed them. “Do-it-yourself” manuals were popular among the landowning elite because they offered, as Marcellus promises, a form of self-sufficiency and mastery. Alf Önnerfors has argued that a personal element distinguishes the De medicamentis from similar medical manuals, which are in effect if not fact anonymous. In the letter to his sons, whom he addresses as dulcissimi (“my sweetest”), Marcellus expresses the hope that they and their families will, in case of sickness, find support and remedies in their father's manual, without intervention by doctors (sine medicis intercessione). This emphasis on self-reliance, however, is not meant to exclude others, but to empower oneself to help others; appealing to divina misericordia (“godlike compassion”), Marcellus urges his sons to extend caritas (“caring”
