to find a place along Latin throughout central Europe, also in scholarly areas. The emperor's program of restoring the University of Vienna to its former pre-eminence was also concerned with astrology and astronomy. He realized the potential of the print press when combined with these branches of learning, and employed Georg Tannstetter (who, in 1509, was appointed by Maximilian as the Professor of Astronomy at the University of Vienna and also worked for a joint calendar reform attempt with the Pope) to produce yearly practica and wall calendars. In 1515, Stabius (who also acted as the court astronomer), Dürer and the astronomer Konrad Heinfogel produced the first planispheres of both southern and northerns hemispheres, also the first printed celestial maps. These maps prompted the revival of interest in the field of uranometry throughout Europe. The Ensisheim meteorite fell on earth during the reign of Maximilian (7 November 1492). This was one of the oldest meteorite impacts in recorded history. King Maximilian, who was on his way to a campaign against France, ordered for it to be dug up and preserved at a local church. The meteorite, as a good omen, was utilized for propaganda against France through the use of broadsheets with dramatic pictures under the direction of the poet Sebastian Brandt (as Maximilian defeated a far larger French army to his own in Senlis two months later, the news would spread even more). On the subject of calendars and calendar reform, already in 1484, the famous Flemish scientist Paul of Middelburg dedicated his Praenostica ad viginti annos duratura to Maximilian. His 1513 magnum opus Paulina de recta Paschae celebratione was also dedicated to Maximilian, together with Leo X. In addition to maps, other astrological, geometrical and horological instruments were also developed, chiefly by Stiborius and Stabius, who understood the need to cooperate with the emperors to make these instruments into useful tools for propaganda also. The extraordinarily luxurious planetarium, that took twelve men to carry and was given as a diplomatic gift by Ferdinand I to Suleiman the Magnificent in 1541, originally belonged to Maximilian. He loved to introduce newly invented musical instruments. In 1506, he had a special regal, likely the apfelregal seen in one of Hans Weiditz's woodcuts, built for Paul Hofhaimer. The emperor's favourite musical instrument maker was Hans Georg Neuschel of Nuremberg, who created an improved trombone (Neuschel was a talented trombonist himself). In 1500,
