[2] One author, Restoro d'Arezzo, conflated Orpheus with Artephius in his Composizione del Mondo in 1282.
[4] Artephius has also been misidentified as a Jewish convert,[5] Apollonius of Tyana, Stephanos of Alexandria, Al-Tughrai,[3] and Ibn Umail.
[4] The discovery of a 13/14th-century copy of Clavis Sapientia confirms that the text was first written in Arabic by a Muslim author.
[4] A Renaissance tradition held that Artephius had been born in the first or second century and died in the twelfth, thanks to having discovered the alchemical elixir that made it possible to prolong life.
[7] The Latin editions of Clavis Sapentia are highly abridged and lack the original diagrams found in the Arabic text.
