Presiding Judge Ganjar Susilo found the 70-year-old guilty of helping steal the stone statues, which date back to the 4th century, and selling them to a Dutch curator for between US$3,500 and US$20,000 each. Replicas made by local stonemasons were put in their place.
The scam was first uncovered by an ex-staffer at the museum in Surakarta, a city on Java island.
"I've given 50 years of my life to service the museum," Darmodipuro said after the verdict was handed down. "It was a big mistake. ... I very much regret it and accept this sentence."
Thieves have long targeted Indonesian antiquities left over from the country's Hindu and Buddhist era. The objects _ mostly statues and temple reliefs _ are in demand by wealthy locals and collectors on the international market.
The statues stolen from the Radya Pustaka Museum were recovered in a raid on the house of a wealthy businessman in the capital, Jakarta.
