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.
