The Theriaca (Ancient Greek: Θηριακά) is the longest surviving work of the 2nd-century BC Greek poet Nicander of Colophon.
It is a 958-line hexameter poem describing the nature of venomous creatures, including snakes, spiders and scorpions, and the wounds that they inflict.[1]
Nicander also wrote the companion work Alexipharmaca, which explored other poisons and venoms.
