1911 Encyclopædia Britannica/Rudra

RUDRA (probably from the root rud, “to howl,” hence “the howler”), in Hindu Vedic mythology, a storm god, and father of the Maruts who are frequently called Rudriyas. He shoots tempests at the earth, but is not essentially a malevolent deity, being invoked as a protector of cattle. In the Atharvaveda he is lord of life and death, and in later Hinduism one of the Hindu trinity, the god Siva.
