Amelius (Gentilianus)

Amelius Gentilianus appears in late‑antique sources as a human philosopher active in the mid‑3rd century CE. Sources describe him as either a native of Apamea or of Tuscany/Etruria and place him in Rome by about 246 CE, where he began attending Plotinus’s lectures in the third year after Plotinus arrived. He remained a devoted disciple for more than twenty years and retired to Apamea in 269. Porphyry records that Amelius chose the name 'Amelius' (from Greek ἀμέλεια, 'negligence' or 'indifference') as an expression of contempt for worldly things, and that Amelius preferred the altered form 'Amerius' (changing L to R) to suggest 'unification' (Amereia) as a philosophical self‑presentation.

The supplied sources provide no supernatural or fixed physical portrait of Amelius; descriptions concern his scholarly life rather than bodily features. He is variously described as a native of Apamea or Tuscany, a voracious reader and writer, and an industrious memorizer of Numenius’s teachings. Anecdotes in Porphyry’s Life of Plotinus relate Amelius commissioning a likeness of Plotinus, but they do not furnish a contemporaneous physical description of Amelius himself.

Accounts attribute to Amelius intellectual and pedagogical capacities rather than supernatural powers. Porphyry and other sources record that he read and wrote extensively, memorized almost all teachings of Numenius, and produced a large corpus of writings—reported as over one hundred volumes of sayings and commentaries. His principal described work is a forty‑book treatise arguing against attributing Plotinian doctrines to Numenius. He is portrayed as influential in persuading Porphyry of Plotinus’s doctrines and in urging Plotinus to commit his teachings to writing, marking him as a central transmitter and defender within the Neoplatonic school.
