After the death of Sigismund Augustus in 1572, the interest was supposed to be split between his sisters Anna Jagiellon and Catherine Jagiellon. However, Anna did not forward the money to Catherine in Sweden and their conflict became known. The matter of recovering Neapolitan sums was discussed again and again in the general sejm. The issue was often combined with the issue of reopening silver and lead mines in Olkusz that were flooded during the Swedish Deluge. These two matters were often brought up when taxation was discussed as a solution to fiscal issues of the Polish–Lithuanian Commonwealth. It became a proverb that Poland was robbed twice: once by river Baba that flooded Olkusz, and a second time by Queen Bona.
