of ages was ruled by seven planetary angels, in addition to God (the First Intelligence). The historian Martin Hollegger notes though that Maximilian himself did not share the cyclical view of history, typical for their contemporaries, nor believed that their age would be the last age. He had a linear understanding of time – that progresses would make the world better. The kabbalistic elements in the court as well as Trithemius himself influenced the thinking of the famous polymath and occultist Heinrich Cornelius Agrippa (who in Maximilian's time served mainly as secretary, soldier and diplomatic spy). The emperor, having interest in the occult himself, intended to write two books on magic (Zauberpuech) and black magic (Schwartzcunnstpuech) but did not have time for them. Like his father, Maximilian was an alchemist, who at times locked himself up in his room for days to experiment. He collaborated with his sister-in-law Caterina Sforza (her work Experiments records a recipe for an emetic powder attributed to him). He sponsored such experiments too. According to Leonhard Thurneysser, in 1499 an alchemist named Schwichard Fronberger set up for him an astro-alchemical project that would theoretically produce silver in 1547 and gold in 1598 (Maximilian was 40 in 1499). In his circle, Reisch and Agrippa were also interested in alchemy, although Agrippa joined a secret society that did not allow publishing about this topic. The establishment of the new Courts and the formal Reception of Roman Law in 1495 led to the formation of a professional lawyer class as well as a bureaucratic judiciary. Legal scholars trained in mos italicus (either in Italian universities or in newly established German universities) became in demand. Among the prominent lawyers and legal scholars who served Maximilian in various capacities and provided legal advices to the emperor were Mercurino Gattinara, Sebastian Brandt and Ulrich Zasius. Together with the aristocrats and the literati (who participated in Maximilian's propaganda and intellectual projects), the lawyers and legal scholars became one of three main groups in Maximilian's court. Konrad Stürtzel, the Chancellor, belonged to this group. In Maximilian's court – more egalitarian than any previous German or Imperial court, with its burghers and peasants – all these groups were treated equally in promotions and rewards. The individuals were also blending in many respects, usually through marriage alliances. Maximilian was an energetic patron of the library.
