Boraspati ni Tano

[1] Boraspati ni Tano is the Earth deity in Batak mythology representing fertility, wealth and the underworld.

[2] The name Boraspati ni Tano is borrowed from Sanskrit Brihaspati, a Hindu astrological representation of Jupiter and the day of the week Thursday.

[3] Boraspati ni Tano is one of the most important personification of natural forces of Batak's cosmology, together with Boru Saniang Naga (water deity).

Because of this, Boraspati ni Tano was frequently mentioned in the public invocations (Batak tonggo-tonggo) as a very important figure.

Boraspati ni Tano was invoked in the beginning before starting any kind of works e.g. village founding and establishing houses (specifically when the offering-pole was planted into the ground).
