Spectacular archaeological discoveries were made during the 1970s and 1980s in Bulgaria and North Aegean Greece which sparked international interest in the forgotten Odrysian kingdom of Thrace. Here, for the first time, these and earlier discoveries are presented in their archaeological and historical context. The Thracians were the fabulously wealthy and populous neighbours of the ancient Greeks, whose golden age began in the fifth century BC when an inter-tribal state was created by the ruling dynasty of the tribe - the Odrysians. A vogue in the Greek world for Orpheus the Thracian coincided with the period of the Odrysians's greatest prominence. Not only does this book analyse the fascinating cultural amalgam of native, Persian, and Greek elements by the Odrysian governing elite, it also provides new data on the external relations of Athens, Thasos, and Macedon in the classical and early Hellenistic periods.
