pin down the treasure's origins:
It is now agreed that the treasure belonged to the King (later Emperor) Charles IV of the House of Luxembourg. Around 1348, needing funds to support his claim to the King of the Romans, Charles pawned various items to the Jewish banker Muscho (Moshe, Mojżesz) in Środa . . . Soon afterwards, the black plague visited Środa. Muscho was not heard of again and it is believed that he either fled from the plague-struck town, died of plague, or perhaps fell victim to pogroms as Jews were blamed for spreading the plague. What is certain is that no one ever reclaimed the treasure, which was left hidden somewhere in the town for hundreds of years.The crown probably belonged to Charles' first wife, Blanche of Valois; the crow and some of the other pieces have wedding motifs, so they may have parts of her trousseau.
