Aelius Marcianus, a lawyer of the early 3rd cent. ce, probably from the eastern provinces. Mainly a teacher, he does not seem to have given responsa (consultative opinions). His extensive knowledge of the rescripts (replies to petitions) of Severus and Caracalla might be explained by a connection with *Ulpianus, whose style is similar, and of whom he may have been a pupil. He is not known to have held public office. Author of several monographs and commentaries published after Caracalla's death in 217, he is best known for his large-scale teaching manual, sixteen books (libri) of Institutiones. Though other lawyers do not seem to have cited him, Justinian's compilers admired his clarity and measured judgement and selected over 280 passages from his work for the Digesta (see justinian's codification).
