atharvaNa vEda (also called atharva vEda) is the fourth of the Indian Sacred Books - The Vedas. Though the Vedas are four in number, initially there seemed to be only three: Rig Veda, Yajur Veda, and Sama Veda. Atharvana Veda was apparently added later.

AtharvaNa vEda is more akin to sub-vEdas like AyurvEda (traditional Indian medical science), dhanurvEda (archery), sthapatya vEda (architecture and sculpture), arthaSAstra (economics) etc.
