Indra, a heroic god, slayer of Vritra and destroyer of the Vala, liberator of the cows and the rivers; Agni the sacrificial fire and messenger of the gods; and Soma, the ritual drink dedicated to Indra, are the most prominent deities.
There are two major groups of gods: the Devas and the Asuras. Unlike in later Vedic texts and in Hinduism, the Asuras are not yet demonized, Mitra and Varuna being their most prominent members. Aditi is the mother both of Agni and of the Adityas or Asuras, led by Mitra and Varuna, with Aryaman, Bhaga, Ansa and Daksha.
Surya is the personification of the Sun, but Savitr, Vivasvant, the Ashvins and the Rbhus, semi-divine craftsmen, also have aspects of solar deities. Other natural phenomena deified include Vayu, (the wind), Dyaus and Prithivi (Heaven and Earth), Dyaus continuing Dyeus, the chief god of the Proto-Indo-European religion, and Ushas (the dawn), the most prominent goddess of the Rigveda, and Apas (the waters).
The names of Indra, Mitra, Varuna and the Nasatyas have also attested in a Mitanni treaty, suggesting that some of the religion of the Mitannis was very close to that of the Rigveda.
List of Rigvedic deities by a number of dedicated hymns, after Griffith (1888). Some dedications are to paired deities, such as Indra-Agni, Mitra-Varuna, Soma-Rudra, here counted double. Vishvadevas (all gods together) have been invoked 70 times.
