In the Ṛg Veda, the creative principle, personified as the deva who creates the world through sacrifice; he is therefore often identified with Prajāpati. He is imagined as having eyes, faces, arms, and feet on all sides. In Purāṇic mythology Viśvakarman is elided with Tvaṣṭṛ, and conceptualized as the universal architect (i.e. the architect of the gods). He presides over the Sthāpatyaveda.
