In 47, Sosibius gave Claudius a reminder of the power and wealth which threatened the Emperor's throne. His tutor then, as part of his mother's contrivances, told the emperor of Decimus Valerius Asiaticus's involvement in the murder of Caligula and of his growing popularity in Rome. Sosibius went on, saying Asiaticus meant to rally Roman legions in Germany against the throne. Asiaticus was apprehended immediately, and brought to Rome in chains. Sullius successfully pursued charges against other equestrians in the Senate. According to Cassius Dio, Asiaticus was put to death as a favor to Messalina for his property (the Gardens of Lucullus).
