The legend that Glabrio was an early
convert to Christianity was suggested to be true when in 1888 a tomb of the Acilii Glabriones was discovered adjacent to the
Catacomb of Priscilla. Although the inscriptions from the tomb mentioning the family were inscribed in a script used generations later than this Manius Acilius Glabrio and his wife Priscilla, at the time numerous experts eagerly cited this archaeological find as certain proof of the story.
[9] It was in 1931 when P. Styger was able to show the stone inscriptions did not properly belong to the chamber, but had been part of a sepulchre that was demolished in the construction of the Basilica of San Silvester after the fourth century. Half a century later, F. Tolotti was able to confirm Styger's interpretation when he identified the funerary area the inscriptions had come from.
