Wyvern wyvern is thought to have derived from the figure of the dragon encountered by Trajan's legions in Dacia. It may be the origin of the red dragon of Wales and the golden dragon of the Kingdom of Wessex carried at the Battle of Burford in AD 752. The concept of winged snakes is common in cultures around the Mediterranean, with a notable example being the Egyptian goddess Wadjet. The oldest creatures outright referred to as "winged dragons" are Helios' chariot steeds, which aid Medea. Wyverns are very similar to dragons, and in many languages, cultures and contexts no clear distinction
Wyvern the coat of arms of the Tilley family. The kings of Aragon of the House of Barcelona since Peter IV used a wyvern as a crest on their helmets. Nowadays this symbol has been officially adopted as the coat of arms of the Generalitat Valenciana (Valencian Parliament and Government). The arms of the Worshipful Society of Apothecaries depict a wyvern, symbolising disease, being overcome by Apollo, symbolising medicine. The wyvern is also a fairly popular commercial logo or mascot, especially in Wales and what was once the West Country Kingdom of Wessex, but also farther afield in Herefordshire and Worcestershire,
