A number of ancient civilizations, including the Thracians, Ancient Greeks, Scythians, Celts, Ancient Romans, Goths (Ostrogoths and Visigoths), Slavs (East and West Slavs), Varangians and the Bulgars have left their mark on the culture, history and heritage of Bulgaria. Due to this great variety of influences, Bulgaria has adopted many unusual traditions, including nodding to mean "no" and shaking head for when you mean "yes". Thracian artifacts include numerous temples, tombs, and ancient rites and rituals, while ancient Bulgars have left traces of their heritage in statehood, early architecture, music and dances. Thracian rituals such as the Tryphon Zarezan which is dedicated to Saint Tryphon of Campsada, Kukeri and Martenitza are to this day kept alive in the modern Bulgarian culture.T
