In Finnish mythology, Ajattar (also spelled Aiatar, Ajattaro or Ajattara) is a spirit known as "Devil of the Woods". It is an evil female spirit that manifests as a snake or dragon. Ajatar is said to be the mother of the devil. She spreads disease and pestilence, any that look at her become ill, and she suckles serpents.
The word "ajatar" is possibly derived from the verb ajattaa, "make to pursue", of Finnish word ajaa , "to pursue".
