Japheth /ˈdʒeɪfɛθ/ (Hebrew: יֶפֶת Yép̄eṯ, in pausa יָפֶת Yā́p̄eṯ; Greek: Ἰάφεθ Iápheth; Latin: Iafeth, Iapheth, Iaphethus, Iapetus), is one of the three sons of Noah in the Book of Genesis, where he plays a role in the story of Noah’s drunkenness and the curse of Ham, and subsequently in the Table of Nations as the ancestor of the peoples of the Aegean, Anatolia, and elsewhere.[1] In medieval and early modern European tradition he was considered to be the progenitor of European and, later, East Asian peoples.[2][3][4] […]
In the seventh century, Isidore of Seville published his noted history, in which he traces the origins of most of the nations of Europe back to Japheth.[16][17] Scholars in almost every European nation continued to repeat and develop Saint Isidore’s assertion of descent from Noah through Japheth into the nineteenth century.[4]

“Iapetus as the progenitor of mankind has been equated with Japheth (יֶפֶת), the son of Noah, based on the similarity of their names and the tradition, reported by Josephus (Antiquities of the Jews), which made Japheth the ancestor of the “Japhetites”. Iapetus was linked to Japheth by 17th-century theologian Matthew Poole[9] and, more recently, by Robert Graves[10] and by John Pairman Brown.[11]”

“Iapetus’s wife is normally a daughter of Oceanus and Tethys named either Clymene (according to Hesiod[13] and Hyginus) or Asia (according to Pseudo-Apollodorus). “
