To mark the 400th anniversary of their deaths, an international forensic team has reconstructed the faces of the Three Košice Martyrs - Catholic priests Mark Križin, Melchior Grodziecki and Stephen Pongracz, who were killed during a Protestant upheaval in 1619. The final facial reconstructions were produced by renowned Brazilian 3D-designer Cicero Moraes, who in the past engaged in a similar effort with Saint Anthony of Padua, for example. The remains of the three martyrs are stored in reliquaries in Trnava and Esztergom, Hungary. Church historian Peter Zubko said that an examination of the bones had revealed the cruelty of the perpetrators. A major Protestant rebellion against the Habsburgs erupted in the Czech lands in 1619. It was joined by Lutherans in the Kingdom of Hungary, who called on Prince of Transylvania Gabriel Bethlen, also a Protestant, to become their leader. He sent a strong military force to the Kingdom of Hungary and conquered most of present-day Slovakia.
