At that point the monastic community undertook renovations of the basilica . In the course of this work , on 2 August 1052 the remains of various saints , including Maximus the Confessor , Felicitas of Padua , Julian the Hospitaller and those identified as the Holy Innocents , were exhumed . In 1110 the abbey was sacked by the troops of the future Holy Roman Emperor Henry V during his invasion of Lombardy , in order to punish the monks for their loyalty to Pope Pascal II . The basilica complex was devastated in 1117 by a very strong earthquake which wreaked havoc throughout northern Italy and Germany . After the basilica and monastery were rebuilt , excavations resumed and in 1174 the remains of the patroness of the abbey was discovered , as were those identified in 1177 as those of Luke the Evangelist
