Variations: Parea, Parias, Paruas, Pharias, Parous, Baron, Pagerina, Anguis Aesculapij, Aesculapian Snake


The Pareas is briefly mentioned in the Pharsalia’s catalogue of Libyan serpents. It always travels on its tail, leaving a furrow behind it in the ground. Its bite is harmless and gentle, and so it was consecrated to Asclepius, god of healers. Topsell classifies it among the innocent serpents.

Aelian describes it as being red with sharp eyes and a wide mouth. Topsell, on the other hand, gave its length as four spans, and its color as yellow with two long streaks down its side. Aldrovandi describes the pareas as being yellowish below and black above, with possible variations of green and white along its length. He dismisses the claim that it has a crest.

The tendency of the pareas to travel while holding itself clear of the ground has led to its association with the Eden serpent, which did not creep along the ground prior to being cursed. This claim has been contested by Alexander Neckham and Petrus Comestor, as the pareas very clearly does not conform to that curse. Petrus concluded that the curse must only have affected the individual serpent of Eden, leaving other snakes – including the pareas – uncursed.
