In Roman and Merovingian times it was customary to declare panegyrics. These poetical declarations were held for amusement or propaganda, to entertain guests and please rulers. Panegyrics played an important role in the transmission of culture. A common panegyrical device was anachronism, the use of archaic names for contemporary things. Romans were often called "Trojans" and Salian Franks were called "Sicambri". A notable example related by the sixth-century historian Gregory of Tours states that the Merovingian Frankish leader Clovis I, on the occasion of his baptism into the Catholic faith, was referred to as a Sicamber by Remigius, the officiating bishop of Rheims. At the crucial moment of Clovis' baptism, Remigius declared, "Bend down your head, Sicamber. Honour what you have burnt. Burn what you have honoured." It is likely that in this way a link between the Sicambri and the Salian Franks, who were Clovis's people, was being invoked. Further examples of Salians being called Sicambri can be found in the "Panegyrici Latini", the "Life of King Sigismund", the "Life of King Dagobert", and other sources.
