Sculptures depicting the heads of Saints Cassius & Florentius in front of Bonn Minster.
Originally the Minster was the collegiate church of Saints Cassius and Florentius, who were Roman legionaries of the legendary all-Christian Theban Legion. The legion's garrison, according to legend, was in the Egyptian town of Thebes. Roman EmperorMaximianus Herculius ordered the legion to march to Gaul and assist in subduing rebels from Burgundy. At some point during their march, the legion refused to follow the emperor's orders either to kill fellow Christians or to worship Maximianus Herculius as a god. As a result, a large number of legionaries were martyred in Agaunum, now named Saint Maurice-en-Valais after Saint Maurice. According to legend, Saints Cassius and Florentius, who were under the command of Saint Gereon, were beheaded for their religious beliefs at the present location of the Minster.
