The Questing Beast (Old French: beste glatisant, Modern French: bête glatissante), also called the Bizarre Beast or the Beste Glatisant is a legendary creature or a cross-animal monster from Arthurian mythology. Its appearance is described as a bizarre and hybrid mix of different animals; The head and neck of a serpent, the body of a leopard, hindquarters/haunches of a lion, feet of a hart (deer), and its body is covered in spots, often likened to a leopard’s markings.

This creature makes a strange barking or “questing” noise — like a pack of hounds crying from inside its belly, that’s why they named this beast because of these sounds comes from the great noise that it emits from its belly, a barking like "thirty couple hounds questing". And it is usually portrayed as elusive and difficult to catch, symbolizing a long and often futile pursuit.
The Questing Beast is most famously hunted by King Pellinore, and later by Sir Palamedes and Sir Percival, among others. It represents an eternal or cursed quest and is often used as a metaphor for impossible or obsessive pursuits.
