In Greek mythology, Broteas is a son of Tantalus (by Dione, Euryanassa, or Eurythemista) and brother of Niobe and Pelops. Apollodorus makes him a hunter who slighted Artemis, boasted that fire could not harm him, and was driven mad to cast himself into the flames. Pausanias credits him with carving the Magnesians' ancient rock image of the Mother of the Gods on Mount Sipylus.

I.Artemis and the pyre
Apollodorus's Epitome records that Broteas refused honor to Artemis and claimed fire could not hurt him; the goddess drove him mad so that he threw himself into the flames. He is sometimes compared to Actaeon as a hunter whose death is framed as divine retribution. A son Tantalus, named for the grandfather, is also attested.
Ovid's Ibis alludes briefly to Broteas's self-immolation; later Renaissance notes turned "Brotheus" into a deformed son of Vulcan who leapt into fire — a separate literary strand from the Tantalid hunter.
II.Sipylus and the Mother
Pausanias reports that Magnesians north of Sipylus ascribed their oldest image of the Mother of the Gods on the rock Coddinus to Broteas son of Tantalus, tying him to the same Anatolian landscape as Niobe and Pelops. Modern archaeology identifies a Hittite rock relief near Manisa with that traditional site.
A Lapith named Broteas who dies in the Centauromachy (Ovid) is a different minor figure; the atlas node broteas is the Tantalid.
