The building of the Church of the Assumption was also financed by Hetman Saghaidachny and the Moldavian noblemen Pavel, Jeremiah and Simon Mogila. This accounts for its second name – Voloshskaya (from the word Valakhia, meaning Moldavia).
Work was often interrupted due to lack of finances. In 1592 the Fraternity dispatched envoys to Fyodor Ioanovich, King of Muscovy, who contributed to the construction in money and furs. The internal wall of the central cupola bears the coats of arms of Russia, Moldavia and the Fraternity and the inscription:
“The Gracious Tsar (King) and the Great Prince of Muscovy-Russia was the benefactor of this church.”The vaults of the Church contain the tombs of Ivan podkova, a Cossack from Zaporozhye who became a Moldavian nobleman and was executed in Lvov in 1578 and of Constantine Kornyact (1517-1603) and other prominent members of the brotherhood. Kornyact, a Greek from Crete, came to Lvov from Moldavia, made a fortune as a wine merchant, had control of the customs duties and collected royal taxes. He played an important role in the business and cultural life of Lvov at the end of the 16th century. “
