Квинт Гортензий Гортал
Velleius' subject matter consists largely of historical highlights and character portraits, omitting subtler if equally important details. He draws upon the historical writings of Cato the Elder, Quintus Hortensius, Gnaeus Pompeius Trogus, Cornelius Nepos, and Livy, most of which have been lost. He also devotes some attention to Greek and Roman literature, and records unique details about Lucius Afranius and Lucius Pomponius, but he curiously omits any mention of important literary figures such as Plautus, Horace, and Propertius. According to Velleius, the peak of perfection in any literary field is arrived at quickly by the first arrivals. However, this was not an original insight, but a standard view of his time.
