Dicaearchus of Messana (/ˌdɪkeɪˈɑːrkəs ... məˈsɑːnə/; Greek: Δικαίαρχος Dikaiarkhos; c. 370/350 – c. post 323 BC), also written Dikaiarchos (/ˈdɪkaɪɑːrk/), was a Greek philosopher, geographer and author. Dicaearchus was a student of Aristotle in the Lyceum. Very little of his work remains extant. He wrote on geography and the history of Greece, of which his most important work was his Life of Greece. Although modern scholars often consider him a pioneer in the field of cartography, this is based on a misinterpretation of a reference in Cicero[1] to Dicaearchus's tabulae, which does not refer to any maps made by Dicaearchus but is a pun on account books and refers to Dicaearchus's Descent into the Sanctuary of Trophonius.[2] He also wrote books on ancient Greek poets, philosophy and politics.
