Pliny the Elder [1st century CE] (Natural History, Book 10, 70): The pegasus bird with a horse's head and the griffin with ears and a terrible hooked beak - the former said to be found in Scythia and the latter in Ethiopia - I judge to be fabulous... - [Rackham translation]

Gaius Julius Solinus [3rd century CE] (De mirabilibus mundi / Polyhistor, Chapter 30.27): The pegasus is bird of these skies [Ethiopia], but this pegasus has nothing equine about it excepting its ears.- [Arwen Apps translation, 2011]

Thomas of Cantimpré [circa 1230-1245 CE] (Liber de natura rerum, Quadrupeds 4.89): The pegasus, as Pliny says, is a large and fearsome animal in Ethiopia. It has the body of a horse, wings like an eagle, but much larger, the head is equipped with horns and it is truly monstrous, such that almost all living things are scared of it. They, aided in their flight by a wondrous rowing of wings, they run rather than fly and having struck the air with the power of the wings, drive the wind to the image of a tornado. They devour many foods, they are moved by restlessness, they are unsafe for animals, and the most unsafe for humankind. - [Translation from The Thomas Project]
