In a fascinating turn of events for archaeology and astronomy enthusiasts, a 500-year-old compass that might have belonged to the legendary Renaissance astronomer Nicolaus Copernicus has been unearthed. This discovery was made by the Warminska Grupa Eksploracyjna, an amateur archaeological exploration group in Poland.
The compass, crafted from a copper alloy, was found buried beneath the gardens of the Archcathedral Basilica of the Assumption of the Blessed Virgin Mary and Saint Andrew, commonly known as Frombork Cathedral, located in northern Poland.
The Warminska Grupa Eksploracyjna shared their remarkable find on social media, describing the process that led to the discovery. They utilized ground-penetrating radar to explore beneath the cathedral’s grounds, a technique that has proven invaluable in archaeological digs for its ability to reveal hidden structures without disturbing the earth.
Their exploration led them to an underground chamber with three separate tunnels, which they enthusiastically described as a significant breakthrough.
This astounding find takes us back to the era when Copernicus made his revolutionary discoveries, stated Misja Skarb, a member of the Warminska Grupa Eksploracyjna, and opens up new possibilities for understanding his methods of work. Although there is no concrete evidence yet to confirm that the compass was personally used by Copernicus, the circumstances surrounding the discovery suggest a strong connection.
Copernicus lived and worked near Frombork Cathedral, which was an essential site during his life. In the 15th century, while studying astronomy at the University of Bologna in Italy, Copernicus observed his first lunar eclipse.
Around this time, his maternal uncle and protector, Lucas Watzenrode, who was the Bishop of Varmia, appointed him as a canon of the cathedral in Frombork. This position provided Copernicus with a generous income, which allowed him to fund his private studies.
Copernicus’s most significant contribution to astronomy, the heliocentric model, was detailed in his 1543 work De revolutionibus orbium coelestium. This groundbreaking book challenged the prevailing geocentric views endorsed by the Catholic Church, proposing instead that the Earth revolves around the Sun.
The compass found at Frombork bears a remarkable resemblance to the one depicted in Jan Matejko’s 1873 painting, Astronomer Copernicus, or Conversations with God. In this painting, Copernicus is shown standing on a balcony of the Frombork Cathedral, gazing at the sky with a compass in his left hand. This visual connection further strengthens the link between the discovered instrument and the renowned astronomer.
Moreover, the compass was found close to the location where Copernicus’s remains were uncovered. For many years, it was believed that Copernicus was buried within the cathedral, but it wasn’t until 2005 that archaeologists located a partial skull matching his description.
The Warminska Grupa Eksploracyjna suggests that the compass might have belonged to Copernicus, supported by a Polish legend that describes how the astronomer used secret tunnels to move between the cathedral and the nearby castle where he worked. The compass may have been misplaced during one of his daily travels.
This discovery marks the third such instrument found in Poland and the second from the cathedral grounds. The compass has been sent to the Conservator of Monuments of Poland for testing and preservation. Once conserved, it is expected to be displayed at the Nicolaus Copernicus Museum, located nearby, offering visitors a tangible link to the history of science and the life of a man who fundamentally changed our understanding of the cosmos.
