The Trinovantes reappeared in history when they participated in Boudica's revolt against the Roman Empire in 60 AD. Their name was given to one of the "civitates" of Roman Britain, whose chief town was Caesaromagus (modern Chelmsford, Essex). The style of their rich burials (see facies of Aylesford) is of continental origin and evidence of their affiliation to the Belgic people. Their name was re-used as "Trinovantum", the supposed original name of London, by Geoffrey of Monmouth in his largely fictional "Historia Regum Britanniae", in which he claimed the name derived from "Troi-novantum" or "New Troy", connecting this with the legend that Britain was founded by Brutus and other refugees from the Trojan War.
