Atharva Veda 

The Vedic literature is broadly divided into two categories viz. Shruti and Smriti. Shruti describes the sacred texts comprising the central canon of Hinduism viz. Vedas, Brahmanas, Aranyakas, & Upanishads. Smiriti literally means “that which is remembered,” and it is entire body of the post Vedic Classical Sanskrit literature. It comprises Vedanga, Shad darsana, Puranas, Itihasa, Upveda, Tantras, Agamas, Upangs. There is another post Vedic class of Sanskrit literature called Epics which includes Ramayana and Mahabharta.
