De antiquitate Paterni soli et de rebus Bulgaricis

De antiquitate Paterni soli et de rebus Bulgaricis ("On the antiquity of the fatherland and the deeds of the Bulgarians") is a historical treatise written in Latin by Bulgarian Catholic archbishop Petar Bogdan (1601–1674).

The existence of the treatise was known from Petar Bogdan's letters, but its text was regarded as lost.

In 2017, Prof. Liliya Ilieva encountered the full text of the treatise in the University of Modena's Biblioteca Estense.

All 70 chapters of the treatise were published as a book including a facsimile, a Bulgarian translation and commentary by Sofia University in 2020.

[3] A reproduction of the treatise is being displayed as part of a temporary exhibition at the National Archaeological Museum in Sofia.
