Viganj Miloševic deceased. A part of the grave-stone from his grave in Kocerin field nearby Siroki Brijeg is conserved, with the inscription on it written in Bosnian/Croatoan/Western Cyrillic (this alphabet being known as "bosancica"), which states: "+ Va ime oca i sina i svet(a)go d(u)ha. Amin! Se (ovdje) lezo Vig(a)ri Miloševic. Sluzi banu Stipanu, i kralu T(vrt')ku, i kralu Dabisi i kralici Grubi, i krala Ostoju. I u to vrime doide, i svadi se Ostoja kral' s Hercegom i z Bosn(o)m i na Ugre poe Ostoja. To vrime mene Vigna doide koncina i legoh na svom plemenitom pod Kocerinom. I molu vas, ne nastupaite na me! Ja s(a)m bil kako vi (j)este, vi cete biti kako (j)esam ja."
The approximate translation of this inscription would be as follows:
"+ In the name of the Father and the Son and the Holy Spirit. Amen! (Here) lieth Vigari Milosevic. Served banus Stipan, and king Tvrtko and king Dabisa, and queen Gruba, and king Ostoja. And the time came, when king Ostoja was quarelling with the Herzog and with Bosnia, and when Ostoja fetched Ugre. At that time I Vigna came to my end and laid down on my noble Kocerina. I beg you, do not step on me! I was as such as thou art, thou willest be as such as I am."
