Dicaearchus (also Dicearchos, Dicearchus or Dikæarchus, Greek Δικαιαρχος; circa 350 BC – circa 285 BC) was a Greek philosopher, cartographer, geographer, mathematician and author. He was born in Messine (also Messana, Messene; present-day Messina). Dicaearchus was Aristotle's student in Lyceum. Very little of his work remains extant. He made geometric constructions of a hyperbola and a parabola and worked mainly in the field of cartography, where he was among the first to use geographical coordinates.
