Leocadius, the leading Senator of Gaul had believed in the pagan gods, wrote Gregory in his History of the Franks, but now became a Christian and turned his house into a church.
There the Christians established their church, later to become the cathedral where they kept relics of Saint Stephen the first Christian martyr.
Later, Leocadius having retired to the region near Déols and wishing to prepare for his own demise, ordered a magnificent sarcophagus of Italian marble to be prepared for himself. However, tragically his son Lusorius, was to die before him. A disciple of Saint Ursinus of Bourges, Lusorius died a mere eight days after receiving his baptism. In his grief Leocadius had his son entombed in the sarcophagus which had been prepared for his own death. Within a short period miracles began to be recorded by the tomb and Lusorius’ relics gained a reputation for their thaumaturgical properties.
Leocadius was subsequently laid to rest in a simple stone coffin placed along side his son’s.
