Eumolpus

Eumolpus was a legendary Thracian king who, according to Greek mythology, established the City of Eumolpias, also called Eumolpiada (present-day Plovdiv) around 1200 BC (or 1350 BC), naming it after himself. His name may derive from eumelus "sweet melody". He is also referred to as Evmpolp in Bulgarian and Russian, which may be more or less related to his original name. If there is any truth in this myth then Plovdiv is one of the oldest still functioning cities in Europe.
