Esterka (Estera) refers to a mythical Jewish mistress of Casimir the Great, the historical King of Poland who reigned between 1333 and 1370. Medieval Polish and Jewish chroniclers considered the legend as historical fact and report a wonderful love story between the beautiful Jewess and the great monarch.[1]
