Origins

From Etruscan 𐌐𐌄𐌓𐌔𐌖 (persu), though the ultimate origin is uncertain. Possibly a late, unaspirated version of 𐌘𐌄𐌓𐌔𐌖 (φersu, “mask”). The name has been confused with Ancient Greek Περσεύς (Perseús, “Perseus”) because of some Etruscan artifacts transcribing the hero's name with the same spelling.
