Marcin Bylica
Marcin Bylica entered the world around 1433 in the town of Olkusz. His father Jan worked as a caretaker for the local waterworks and held the status of a burgher. This background placed him within the urban middle class rather than among the nobility or peasantry. He likely received his earliest education at a parish school within that same Polish town. Later he traveled to the University of Cracow to pursue advanced studies. There he studied under the guidance of Marcin Król z Żurawicy, an established astronomer of the era.
Bylica arrived in Rome during 1464 serving as an astrologer to a cardinal. That cardinal was either Pietro Barbo who became Pope Paul II or Rodrigo Borgia who later rose to become Alexander VI. It was here in the Italian capital that he encountered Johannes Müller von Königsberg known as Regiomontanus. The two men began a productive partnership that would reshape their understanding of planetary motion. They co-authored Disputationes inter Viennensem et Cracoviensem super Cremonensia in planetarum theoriae deliramenta. This work served as a sharp critique of Gerard of Cremona's outdated astronomical theories. Their collaboration produced new astronomical tables designed to improve predictive accuracy.
John Vitéz archbishop of Esztergom and his nephew Janus Pannonius bishop of Pécs invited Bylica to join their newly founded university in Presburg. This institution was called Universitas Istropolitana. They worked together inside the palace at Esztergom where John Vitéz had installed an observatory. In 1467 they completed the Tabulæ directionum et profectionum. These tables allowed astrologers to predict future events based on a person's birth date. The publication proved immensely popular with eleven printed editions appearing by 1626. The work established their reputation across Central Europe before they moved on to other commissions.
In the spring of 1468 Marcin Bylica became the official astrologer for Matthias Corvinus King of Hungary. This appointment followed a public disputation held almost certainly in Presburg. His opponent was Johannes Stercz who argued about the horoscope of the son born to count János Rozgon. Bylica claimed that Stercz suffered humiliation during the debate. King Matthias declared Bylica the winner and awarded him one hundred florins. He subsequently became one of the closest councilors to the monarch. This victory elevated his status from scholar to political insider within the Hungarian court.
At the end of Nicolaus Copernicus's time there in 1494 a large globe arrived at the University of Cracow. Two astrolabes and a triquetrum instrument also came as gifts from Bylica's estate. These items formed part of an important collection of books and astronomical tools he bequeathed upon death. The library included works by Regiomontanus and Georg von Peuerbach alongside the Tractatus Astrarii by Giovanni Dondi dell'Orologio. A street in Olkusz now bears his name to honor this legacy. The instruments survived centuries to influence future astronomers including Copernicus himself.
