Nav (Croatian, Czech, Slovak: Nav, Polish: Nawia, Russian: Навь, Serbian: Нав, Slovene: Navje, Ukrainian: Мавка, Mavka or Нявка, Nyavka)[a] is a phrase used to denote the souls of the dead in Slavic mythology. The singular form (Nav or Nawia) is also used as a name for an underworld, over which Veles exercises custody—it is often interpreted as another name for the underground variant of the Vyraj (heaven or paradise).[3]
The words nawia, nav and its other variants are most likely derived from the Proto-Slavic *navь-, meaning "corpse", "deceased".[4] Cognates in other Indo-European languages include Latvian nāve ("death"), Lithuanian nõvis ("death"), Old Prussian nowis ("body, flesh"), Old East Slavic навь (navʹ) ("corpse, dead body") and Gothic 𐌽𐌰𐌿𐍃 (naus, "dead body, corpse").[5]
Nyavka could be cognate with the Sanskrit word Naraka, referring to the concept of hell in Hinduism.[citation needed]
The nawie, nawki, sometimes also referred to as lalki[3] (Polish language; all plural forms) were used as names for the souls of the dead. According to some scholars (namely Stanisław Urbańczyk, among others), this word was a general name for demons arising out of the souls of tragic and premature deaths, killers, warlocks, the murdered and the Drowned Dead.[6] They were said to be hostile and unfavourable towards humans, being jealous of life.[6] In Bulgarian folklore there exists the character of 12 navias that sucked the blood out of women giving birth, whereas in the Ruthenian Primary Chronicle the navias are presented as a demonic personification of the 1092 plague in Polotsk.[4] According to folk tales, the nawie usually took the form of birds.[3]
The phrase Nawia (Polish) or Nav (used across Slavic tongues) was also utilised as a name for the Slavonic underworld, ruled by the god Veles, enclosed away from the world either by a living sea or river, according to some beliefs located deep underground.[3] According to Ruthenian folklore, Veles lived on a swamp in the centre of Nav, where he sat on a golden throne at the base of the Cosmic Tree, wielding a sword.[3] Symbolically, the Nav has also been described as a huge green plain—pasture, onto which Veles guides souls.[3] The entrance to Nav was guarded by a Zmey.[3] It was believed the souls would later be reborn on earth.[7] It is highly likely that these folk beliefs were the inspiration behind the neopagan idea of Jav, Prav and Nav in the literary forgery known as the Book of Veles.
