Amelius (/əˈmiːliəs/; Ancient Greek: Ἀμέλιος), whose family name was Gentilianus, was a Neoplatonist philosopher and writer of the second half of the 3rd century.
[2] Originally a student of the works of Numenius of Apamea, he began attending the lectures of Plotinus in the third year after Plotinus came to Rome,[3] and stayed with him for more than twenty years, until 269, when he retired to Apamea in Syria, the native place of Numenius.
Amelius was not his original name; he seems to have chosen it to express his contempt for worldly things, as the word ἀμέλεια (ameleia) means negligence in Greek.
[7] His principal work was a treatise in forty books arguing against the claim that Numenius should be considered the original author of the doctrines of Plotinus.
[8] Amelius is also cited by Eusebius and others as having quoted with approval the definition of the Logos in the Gospel of John.
