Mārtanda

Martanda (Sanskrit: मार्तंड, romanized: Mārtanda) in Hinduism is the eighth and last of the Vedic solar deities called Adityas.

[1] Mârtânda is etymologically derived from mârta, meaning “dead or undeveloped” (a word connected with mrita, the past participle of mri, "to die") and ânda, "an egg or a bird".

Although many hymns in the Rigveda mention him along with the other Adityas as a form of Surya, as evident from the verse above, Aditi shunned him.

[4] In the post-Vedic period, when the number of Adityas increased to twelve, the name Vivasvat was added to the canon.

However a temple complex nearby named Martand Tirth serves as a modern replacement.
