Tiwaz (Luwian deity) Tiwaz (Luwian deity) Tiwaz (Stem: Tiwad-) was the Luwian Sun-god. He was among the most important gods of the Luwians. The name of the Proto-Anatolian Sun god can be reconstructed as "*Diuod-", which derives from the Proto-Indo-European word "*dei-" ("shine", "glow"). This name is cognate with the Greek Zeus, Latin Jupiter, and Norse Tyr. While Tiwaz (and the related Palaic god Tiyaz) retained a promenant role in the pantheon, the Hittite cognate deity, was largely eclipsed by the Sun goddess of Arinna, becoming a god of the day, especially the day of death. In Luwian cuneiform of the Bronze Age,
King of the Romans revived the title as King of Rome ("Roi de Rome"), styling his son as such at birth. The boy was often known colloquially by this title throughout his short life. However, from 1818 onward, he was styled officially as the Duke of Reichstadt by Emperor Francis I of Austria.
