A brief notice of the otherwise little-known martyrs Caius, Iactus, and Heraclus at Bologna, recorded in the manuscript Martyrology of St. Jerome.
CONCERNING THE HOLY MARTYRS OF BOLOGNA: CAIUS, IACTUS, AND HERACLUS.
Commentary
Caius, Martyr at Bologna (St.) Heraclus, Martyr at Bologna (St.) Iactus, Martyr at Bologna (St.)
These Martyrs are not widely known: they are mentioned in the manuscript Martyrology of St. Jerome in these words: "At Bologna, of Caius, Iactus, Heraclus." Nor should anyone suspect that they are the same as those honored on January 4, namely Hermes, Aggaeus, and Caius; for these too are recorded in the same manuscript Martyrology on the day before the Nones.

Support the Translation
The Acta Sanctorum has never been available in English. This site is translating all of it: January through July are done, August is underway, and the calendar runs to November 10, where the Bollandists stopped in 1940. The scholarship pipeline is built; what remains is a compute bill. Contributions go directly to translating more of the calendar.
The Acta was a funded enterprise for three centuries; the translation runs the same way. Everything here is free and stays free whether you give or not. Wroot Press is a small independent press — an imprint of Wroot Labs LLC, not a charity. Contributions aren't tax-deductible; they buy compute.
