From 17 March to 13 May 2018 Oxford’s Bodleian Library’s new Weston Building will host an exhibition entitled A Renaissance Royal Wedding, marking the 500th anniversary of a landmark sixteenth-century match. On 18 April 1518 the Italian princess Bona Sforza married Sigismund I, King of Poland and Grand Duke of Lithuania, in Cracow cathedral. The lavish nuptials forged links of politics and kinship between the Jagiellonian dynasty of Central Europe and the top families of Renaissance Italy, opening up new channels of communication between the Polish capital and the cities of Italy’s far south – a dynamic exchange of people, books and ideas which continued for decades. Bona Sforza (1494-1557) was a Milanese-Neapolitan princess, from 1518 queen of Poland and from 1524 duchess of Bari, in Puglia, and thus Italian ruler in her own right. King Sigismund (1467-1548) was the scion of a large royal house which, at its peak c. 1525, ruled half of Europe, from Prague to Smolensk. Their wedding was attended by dignitaries and scholars from across Christendom, and their five children – who later ruled in Poland-Lithuania, Sweden and Hungary – presented themselves throughout their lives as Polish-Italian royalty. Bona herself remains a controversial, high-profile figure in Polish memory to this day.
