Marcian of Heraclea (Ancient Greek: Μαρκιανὸς Ἡρακλεώτης, Markianòs Hērakleṓtēs; Latin: Marcianus Heracleënsis; fl.
c. 4th century AD) was a minor Greek geographer from Heraclea Pontica in Late Antiquity.
[8] Only little survives of the epitomes, through citations in the work of Stephanus of Byzantium,[9] but in the case of Menippus there is also some manuscript material.
Apart from his writings, philologists believe that an annotated collection Marcian made of his sources in geography formed the basis of today's extant manuscripts of these earlier works.
Salmasius in his Exercitationes Plinianae[11] placed him about the time of Synesius, who speaks of a Marcian in his "Epistola C" to the Heracleote rhetor Pylaemenes.
