Renovations were soon begun on the basilica. On 2 August 1052, workers putatively exhumed remains of various saints, including Maximus the Confessor, Felicitas of Padua, Julian the Hospitaller, and even some identified as the Holy Innocents. 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. In 1117, the complex was devastated by the powerful Verona earthquake. After the basilica and monastery were rebuilt, excavations resumed and in 1174 the remains of the patroness of the abbey was discovered, and in 1177, some remains attributed to St Luke the Evangelist.
