Sources : Lizard

Aelianus [170-230 CE] (On the Characteristics of Animals, Book 2, chapter 23): Should you strike a lizard with a stick and either on purpose or by accident cut it in two, neither of the two parts is killed, but each moves separately and by itself, and lives, both the one and the other trailing on two feet. Then when the parts meet - for the forepart frequently unites with the hinder - the two join up and coalesce after their separation. And the lizard, now one body, although a scar gives evidence of what it has suffered, yet runs about and maintains its former method of life exactly like one of its kind that has had no such experience. - [Scholfield translation]

Isidore of Seville [7th century CE] (Etymologies, Book 12, 4:34, 37): The lizard (lacertus) is so called because it has arms. As it ages it goes blind; as a cure it goes to an opening in a wall that faces east and looks at the sun, and gets light.
