gave Saint Adalbert's arm to the Emperor. After the meeting, Bolesław escorted Otto III to Magdeburg in Germany where "they celebrated Palm Sunday with great festivity" on 25 March 1000. A continuator of the chronicle of Adémar de Chabannes recorded, decades after the events, that Bolesław also accompanied Emperor Otto from Magdeburg to Aachen where Otto III had Charlemagne's tomb reopened and gave Charlemagne's golden throne to Bolesław. An illustrated Gospel, made for Otto III around 1000, depicted four women symbolising Roma, Gallia, Germania and Sclavinia as doing homage to the Emperor who sat on his throne. Historian Alexis P. Vlasto writes that "Sclavinia" referred to Poland, proving that it was regarded as one of the Christian realms subjected to the Holy Roman Empire in accordance with Otto III's idea of Renovatio imperii—the renewal of the Roman Empire based on a federal concept. Within that framework, Poland, along with Hungary, was upgraded to an eastern foederatus of the Holy Roman Empire, according to historian Jerzy Strzelczyk. Coins struck for Bolesław shortly after his meeting with the emperor bore the inscription Gnezdun Civitas, showing that he regarded Gniezno as his capital. The name of Poland was also recorded on the same coins referring to the Princes Polonie . The title princeps was almost exclusively used in Italy around that time, suggesting that it also represented the Emperor's idea of the renewal of the Roman Empire. However, Otto's premature death on 23 January 1002 put an end to his ambitious plans. The contemporaneous Bruno of Querfurt stated that "nobody lamented" the 22-year-old emperor's "death with greater grief than Bolesław". In 1000 Bolesław issued a law prohibiting hunting beavers and created a office called "Bobrowniczy" whose task was to enforce prince's ordinances. Expansion (1002–1018) Three candidates were competing with each other for the German crown after Otto III's death. One of them, Duke Henry IV of Bavaria, promised the Margraviate of Meissen to Bolesław in exchange for his assistance against Eckard I, Margrave of Meissen who was the most powerful contender. However, Eckard was murdered on 30 April 1002, which enabled Henry of Bavaria to defeat his last opponent, Herman II, Duke of Swabia. Fearing that Henry II would side with elements in the German Church hierarchy which were unfavorable towards Poland, and taking advantage of the chaos that followed Margrave Eckard's death and Henry of Bavaria's conflict with Henry of Schweinfurt, Bolesław
