The Snake “haad” is a creature with mystical powers, and should not be confused with the snake that bites us. In folklore, the "haad" was a harmless grey snake (asp) that was commonly found by every village house. (Bad people did not have a "haad".) The presence of the had protected all the people living in the house.
The snake symbol on a pysanka brings protection from catastrophe.
Snakes are commonly depicted on Trypillian pysanky, as well as on traditional pysanky.
