Reue (variant Reve, Reua) was the Lusitanian sky-god, the supreme deity of the indigenous pantheon of the western Iberian peninsula. His name is cognate with the Indo-European sky-god root *dyews (giving Greek Zeus, Latin Iuppiter, Vedic Dyaus, Norse Tyr, and others), with the typical Celtic-Lusitanian phonetic shifts; Reue is thus the local Iberian reflex of the great Indo-European sky-father, preserved in his Lusitanian name and worship.
The dedicatory inscriptions to Reue are concentrated in the northern Portuguese and northwestern Spanish regions, with epithets that link him to particular sanctuaries (Reue Anabaraegus, Reue Larauco, Reue Reumirago, and others). The pattern is similar to that of Bandua (in the previous entry) — the high-god is multiplied across local sanctuaries, with each manifestation tied to a particular cult-place — but Reue's general theological function as sky-god and supreme deity is more clearly preserved than Bandua's local-protector function. The Lusitanians had a developed sky-religion, with Reue at its summit, and the Roman administrative absorption of the region preserved his cult under the dedications that survive.
Some inscriptions associate Reue with rivers or with mountain-tops, suggesting that the sky-god was conceived as the divinity of the heavens that arched over the land and watered the rivers from above; this aspect connects him with broader Indo-European patterns of the sky-god as the guarantor of natural order and of the cycle of the seasons. The full mythology of Reue is largely lost; the inscriptions preserve names and epithets but no narratives, and we have no Lusitanian texts that would give us the deity's myths.
After the Roman annexation of Lusitania, Reue was identified with Iuppiter Optimus Maximus in the standard Roman provincial syncretism, and the cult continued under this Roman name for several centuries before being extinguished by the Christianization of the peninsula in the fourth and fifth centuries. The figure preserves, however, the clearest evidence we have for the indigenous Lusitanian high-god religion of the pre-Roman period.
