Illyricum sacrum

Illyricum sacrum is a multi-volume historical work written in Latin dealing with history of the Catholic Church in the Balkans. The work was published in eight volumes in the period 1751-1819, with the ninth tome printed in the period 1902-1919 as an appendix to Frane Bulić's Bulletino di archeologia e storia dalmata.

The first five volumes (issued 1751-1775) were authored by Daniele Farlati; the volumes 6 (1800) and 7 (1817), were coauthored by Jacopo Coleti, who also published the last volume in 1819.
