Pomponius, an ancient Latin writer, was born in the province of Batavia in Spain, and flourished in the reign of the emperor Claudius. His three books of Cosmography, or De situ orbis, are written in a concise, perspicuous, and elegant manner; and have been thought worthy of the attention and labours of the ablest critics. Isaac Vossius gave an edition of them in 1658, 4to, with very large and copious notes. To this edition is added, "Julii Honorii oratoris excerptum cosmographicum," first published from the manuscript, and and Ethici cosmographia. Gronovius afterwards published another edition with illustrations by medals. In his last edition are added five books, De Geographia, written by some later author; by Jornandes, as Fabricius conjectures.
