<p style='text-align: justify;'>Georg Peuerbach (Georgius Aunpekh) was born in Peuerbach, near Linz. He studied at the University of Vienna, obtaining his BA in 1448 and MA in 1453. He held positions as court astrologer to the king of Hungary, and then to Emperor Frederick III. The <i>Tabulae eclypsium</i>, originally dedicated to Johann Vitez, Bishop of Grosswardein (now Oradea, Hungary), were probably completed around 1459 and is Peuerbach's most impressive work. The tables allow the calculation of the course of the Sun and Moon and therefore the prediction of eclipses. Although they were based on the <i>Alphonsine Tables</i>, they also contain new computations by Peuerbach. This table shows the 'The true appearances of distance of conjunction in the seventh clime' [<i>Tabula distantiae conjunctionis visibilia vera ad clima septimum</i>]. The illustration is a powerful visual witness to the complexity of Peuerbach's calculations. Such triple-entry tables were among the most arduous to compute.</p>
