Manlius is last mentioned in our sources as one of three ambassadors sent to Delphi in 394 BC to give offerings to Apollo for the successful capture of Veii in 396 BC. The embassy consisted of Manlius and his two colleagues Lucius Valerius Potitus and Lucius Sergius Fidenas (his co-consular in 397 BC). The embassy was to convey an offering to the Oracle of Delphi and to Apollo but was captured by Liparean pirates under the command of the sicilian Greek Timasitheus. The pirates seems to have had a change of heart when they learned of the purpose of the embassy and the three "consulares" were released to continue their journey. This episode should be treated as largely historical as there are a few archaeological and inscriptiorial evidences connected with it. Although there is some disagreement between the sources in regards to the year, Diodorus gives 396 and Livy 394 BC, and the composition of the embassy as only Livy gives us names.
