The bronze-plated wooden chariot is decorated with scenes from Thracian mythology, including figures of a jumping panther and the carving of a mythological animal with the body of a panther and the tail of a dolphin, Ignatov said.
He said the chariot, with wheels measuring 1.2 meters (four feet) across, was found during excavations in a funerary mound that archaeologists believe was the grave of a wealthy Thracian aristocrat, as he was buried along with his belongings.
The team also unearthed well-preserved wooden and leather objects, some of which the archaeologists believe were horse harnesses. The remains of horses were uncovered nearby.
In August, excavations at another ancient Thracian tomb in the same region revealed another four-wheel chariot. Daniela Agre, a senior archaeologist at the Bulgarian Academy of Sciences, had said at the time that it was the first time a completely preserved chariot had been found in Bulgaria. She said previous excavations had only unearthed single parts of chariots
- often because ancient sites had been looted.
Some 10,000 Thracian mounds - part of them covering monumental stone tombs
- are scattered across the country.
Ignatov said up to 90 percent of the tombs in the region have been completely or partially destroyed by treasure hunters who smuggle the most precious objects abroad.
He said the country's Culture Ministry granted euro10,000 ($12,500) for the excavation.
"The money is badly needed because we are in an uneven race with looters who are often better equipped than our teams," he said.
