European dragon in the context of "Ouroboros"

A dragon is a magical legendary creature that appears in the folklore of multiple cultures worldwide. Beliefs about dragons vary considerably through regions, but dragons in Western cultures since the High Middle Ages have often been depicted as winged, horned, and capable of breathing fire. Dragons in Eastern cultures are usually depicted as wingless, four-legged, serpentine creatures with above-average intelligence. Commonalities between dragons' traits are often a hybridization of reptilian, mammalian, and avian features.

A panther is a creature in ancient legend that resembles a big cat with a multicoloured hide.

According to medieval beliefs, after feasting, the panther will sleep in a cave for a total of three days. After this period ends, the panther roars, in the process emitting a sweet smelling odor. This odor draws in any creatures who smell it (the dragon being the only creature immune); they are eaten by the panther, and the cycle begins again.

Worm, wurm or wyrm (Old English: wyrm; Old Norse: ormr; Old High German: wurm), meaning serpent, are archaic terms for dragons (Old English: draca; Old Norse: dreki/*draki; Old High German: trahho) in the wider Germanic mythology and folklore, in which they are often portrayed as large venomous snakes and hoarders of gold. Especially in later tales, however, they share many common features with other dragons in European mythology, such as having wings.

Prominent worms attested in medieval Germanic works include the dragon that killed Beowulf, the central dragon in the Völsung Cycle – Fáfnir, Nidhogg (Old Norse: Níðhǫggr), and the great world serpent, Jǫrmungandr, including subcategories such as lindworms and sea serpents.

Antirrhinum is a genus of plants in the Plantaginaceae family, commonly known as dragon flowers or snapdragons because of the flowers' fancied resemblance to the face of a dragon that opens and closes its mouth when laterally squeezed. They are also sometimes called toadflax or dog flower. They are native to rocky areas of Europe, the United States, Canada, and North Africa. Antirrhinum species are widely used as ornamental plants in borders and as cut flowers.
