Bona Sforza was Queen of Poland and Duchess of Bari and a beloved queen. She became wife of the Polish king Sigismund the Old in 1517. In the 16th century, Cracow was under the influence of Italian culture which was further reinforced by the king's marriage. However, the Polish people owe something else to her. She enriched Poland's monotonous diet by introducing cauliflower, celery, leeks, asparagus, lettuce, and artichokes into cultivation. Hence, the Polish word for "vegetables" — wloszczyzna — means... "of Italian origin".
