 Paulus was a passionate Ciceronian, and perhaps his chief contributions to scholarship are the corrected editions of Cicero's letters and orations ("Epistolae ad familiares" in 1540, "Epistolae ad Atticum" and "Epistolae ad Marcum Iunium Brutum et ad Quintum Ciceronem fratrem" in 1547), his own epistles in a Ciceronian style, and his Latin version of Demosthenes' "Philippics" ("Demosthenis orationes quattuor contra Philippum", 1549).Throughout his life he combined the occupations of a scholar and a printer.As a scholar he is remembered for four elegant Latin treatises on Roman antiquities.
