BISTUA. — At the Synods of Salona in 530 and 533, Andria, bishop of the bestoensis ecclesiae, also appears. His diocese was extensive but very poor; the Synod of Salona in 533 decided to divide it «cum Divinitas propitiata concesserit». It is not known whether this actually took place, since subsequently the invasions of the Avars and Slavs almost completely annihilated Christianity in those regions.
B. Nova was a Roman municipium on the site of the present-day city of Zenica (Bosnia), where a celebrated Early Christian basilica with two naves (basilica gemina) was discovered, while B. Vetus was located at the sources of the Rama, near the village of Varvara. The bishopric of B. was the predecessor of the medieval diocese of Bosnia.
