Phrike

Phrike (Ancient Greek: Φρίκη Phríkē) is the spirit of horror in Greek mythology. Her name literally means "tremor, shivering" (i. e. from fear, horror), and has the same stem as the verb φρίττω (phrittō) "to tremble". The term "Phrike" (personified or not) is widely used in tragedy.

Her Latin equivalent was Horror.
