The Greeks gave us the pegasus, but they also gave us a second stab at a winged horse — one that was a whole lot less regal. The difference in cool factor between the names “pegasus" and “hippalectryon” is also borne out in their appearance. The hippalectryon’s wings came from the fact that it was the front half of a horse with the back half of a rooster. Illustrations do show humans astride them, so in theory they were ridable, but I feel like they weren’t getting you a lot of positive looks in the town square. Real “we have a pegasus at home” vibes.
