 But, in 1992, the discovery of Glagolitic inscriptions in churches along the Orljava river in Slavonia totally changed the picture (churches in Brodski Drenovac, Lovčić, and some others), showing that use of the Glagolitic alphabet was spread from Slavonia also.Sporadic instances aside, Glagolitic survived beyond the 12th century as a primary script in Croatia alone, although from there a brief attempt at reintroduction was made in the West Slavic area in the 14th century.The centre of influence appears to have been in the Kvarner Gulf, though the nature and extent of this influence remain subjects of debate.
