The Kočerin tablet is a tombstone of Viganj Milošević found in Kočerin fields at the end of the 19th century. For a long time, the monument was built into the building of the parish apartment in Kočerin. During the scientific conference "Viganj and its time", the inscription was taken out of the wall and stored in the handy collection of antiquities of the parish of Kočerin.
The plaque served as the headboard of the stećak tombstone of Viganj Milošević, who died in the spring of 1404, so we can assume that the inscription was carved that year. His grave is still located in Kočerinsko polje at the Lipovica site, where a real-size replica of the inscription has been placed. The height of the plate is 137 centimeters and the width is 53 centimeters. The Kočerin plaque has a total of 80 words, making it one of the longest medieval inscriptions written in Cyrillic (Bosnian). Special attention is paid to the stonework of letters and ornaments. Thus, on the upper and side surfaces, the edge is decorated with a vine, a cross, a crescent and a rosette.
The inscription preserves especially valuable historical data, chronologically listing the Bosnian rulers for whom Vignje served, Ban Stjepan Kotromanić, King Tvrtko, King Dabiša, Queen Gruba (Jelena) and King Ostoja. In May 1404, Tvrtko II, with the help of Hrvoje Vukčić Hrvatinić, came into conflict with King Ostoja. In that conflict, Viganj Milošević was most likely killed. Judging by the richness of the tombstone, Viganj was buried with all the honors and attention of the dignitaries of that time.
The text also contains the request "And please don't step on me, I was what you are, you will be what I am", however, archaeological research has confirmed that the grave of Viganj Milosevic was desecrated and looted. The value of this tombstone is reflected in the oldest mention of the name Kočerin.
