The Medieval Bestiary

Hypnale /hypnalis/ 10.3X3.7 cm
The text is taken from Isidor /XII.IV.13—14/. This snake is in the same species with the dipsa. A person bit by the hypnale falls asleep and then dies. This was how Cleopatra died. The hypnal is mentioned by Pseudo-Hugh /11.30/, Albert the Great /XXV.II.33/ and Philippe de Thatin in the section describing the hydra /1671 — 1679/.
