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.[1]
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.
