This article examines the important roles played by gods in the friezes of the Columns of Trajan and Marcus Aurelius and argues that they are treated in a distinctive ‘documentary’ style, comparable in certain ways to accounts of divine action in Roman historiography and designed to produce a compelling narrative effect. First, the Columns and the deities they depict are discussed. The article then looks at cognate descriptions of gods in historiographical texts. Finally, other contemporary monuments that portray the gods are briefly examined to bring out further the distinctive character of the gods on the Columns. This analysis will be seen to have wider implications for our understanding of ‘historical narrative reliefs’ and imperial representation.
