Caecina Mavortius Basilius Decius Caecina Mavortius Basilius Decius ("floruit" 486-510) was a Roman politician under Odoacer's rule. He was consul and "Praefectus urbi" of Rome in 486 and Praetorian prefect of Italy from 486 to 493.
Legion of Antibes The Legion of Antibes was recruited under direction of Pope Pius IX's secretary of state, Giacomo Antonelli, following the September Convention of 1864, to replace French troops garrisoned in Rome, during the closing phase of Italian unification, the "Risorgimento". The September Convention permitted the Pope to keep an army, but it did not give Napoleon III the right to continue to maintain forces in Rome, supporting papal temporal power in the rump Papal States. Nevertheless, at the battle of Mentana, fought 3 November 1867 between French-Papal troops and the Italian volunteers led by Giuseppe Garibaldi, it became public knowledge that the "Legion" was composed of French Imperial recruits, Antibes lying on the Mediterranean coast close to the border with Piedmont: their "services to the Pope were rendered as services to the French Empire," the former Prime Minister of Italy, Francesco Crispi recalled in 1891. "It is singular that on the dead bodies were found livrets French regiments, to which every one of these men belonged, with the number of his matriculation, and with formula of the oath of fidelity to the Emperor."
