The metallurgist, like the blacksmith and, before him, the potter, is a "master of fire." It is by means of fire that he brings about the passage of the material from one state to another. As for the metallurgist, he accelerates the "growth" of ores, he makes them "ripe" in a miraculously short time. Smelting proves to be the means of "acting faster" but also of acting to make a different thing from what already existed in nature. This is why, in archaic societies, smelters and smiths are held to be masters of fire, along with shamans, medicine men, and magicians. But the ambivalent character of metal—laden with powers at once sacred and demonic—is transferred to metallurgists and smiths: they are highly esteemed but are also feared, segregated, or even scorned.
In many mythologies the divine smiths forge the weapons of the gods, thus insuring them victory over dragons or other monstrous beings. In the Canaanite myth, Koshar-wa-Hasis (literally, "Adroit-and-Clever") forges for Baal the two clubs with which he will kill Yam, lord of the seas and underground waters. In the Egyptian version of the myth, Ptah (the potter god) forges the weapons that enable Horus to conquer Seth. Similarly, the divine smith Tvashtr makes Indra's weapons for his battle with Vritra; Hephaestus forges the thunderbolt that will enable Zeus to triumph over Typhon. But the cooperation between the divine smith and the gods is not confined to his help in the final combat for sovereignty over the world. The smith is also the architect and artisan of the gods, supervises the construction of Baal's palace, and equips the sanctuaries of the other divinities. In addition, this godsmith has connections with music and song, just as in a number of societies the smiths and braziers are also musicians, poets, healers, and magicians. It seems, then, that on different levels of culture (an indication of great antiquity) there is an intimate connection between the art of the smith, occult techniques (shamanism, magic, healing, etc.), and the arts of song, of the dance, and of poetry.
