ncient Greeks developed the biographical tradition which we have inherited, although until the 5th century AD, when the word 'biographia' first appears, in Damascius' Life of Isodorus, biographical pieces were called simply "lives" (βιοι: "bioi"). It is quite likely that the Greeks were drawing on a pre-existing eastern tradition; certainly Herodotus' Histories contains more detailed biographical information on Persian kings and subjects than on anyone else, implying he had a Persian source for it.
The earliest surviving pieces which we would identify as biographical are Isocrates' Life of Evagoras and Xenophon's Life of Agesilaos, both from the fifth century BC. Both identified themselves as encomia, or works of praise, and that biography was regarded as a discrete entity from historiography is evidenced by the fact that Xenophon treated King Agesilaos of Sparta twice in his works, once in the above-mentioned encomium and once in his Greek History; evidently the two genres were conceived as making different demands of authors who enrolled in them. Xenophon could present his Cyropaedia, an account of the childhood of the Persian King Cyrus the Great now regarded as so fabulous that it falls rather into a novelistic tradition than a biographical one, as a serious work, without any disclaimers or caveats.
Whereas Thucydides set the benchmark for a historiographical tradition comprising 'conclusions ... drawn from proofs quoted ... [which] may safely be relied upon' (Thuc. 1.21), and offering little explicit judgement on the people with whom he dealt, biographers were quite often more concerned with drawing a moral point from their investigations of their subjects. Parallel Lives by Plutarch, a Greek writing under the Roman empire, is a series of short biographies of eminent men, ancient and contemporary, arranged in pairs comprising one Greek, one Roman, in order that a broad educative point might be extraced from the comparison (for example Mark Antony and...
