50 free Pegasus trivia questions with answers — history quiz, new questions added Aug 2026.
Pegasus trivia for anyone who knows the winged horse from a Disney film, a petrol-station sign or a night sky chart and wants the whole story. The quiz opens with the myth as the Greeks told it: Pegasus springing from Medusa's severed neck alongside his brother Chrysaor, Poseidon as his sire, the spring on Mount Helicon struck open by his hoof, Athena's golden bridle, Bellerophon's ride against the Chimera, and the gadfly Zeus sent to end that hero's flight to Olympus. From there it heads upward. Pegasus was one of Ptolemy's 48 constellations, and its Great Square, its brightest star Enif, the globular cluster M15 and 51 Pegasi b - the first planet found orbiting a Sun-like star, and a Nobel Prize in 2019 - all get questions. So do the modern lives of the horse: the Mobil flying red horse over Dallas, the TriStar Pictures logo, British airborne forces and Pegasus Bridge, the NSO Group's spyware, the world's richest horse race, and Pegasus in Hercules, Clash of the Titans, Fantasia and Barbie. Questions run from easy to expert, and every answer was checked against a reference page and carries its source. See also our Greek mythology and Poseidon quizzes.
