What was discovered

A Greek account of a voyage by the Carthaginian Hanno with some 60 ships to found colonies in Morocco and explore the African Atlantic coast southward. It describes volcanoes, rivers with hippopotamuses and a tribe of 'hairy people'.

Only a Greek version survives (Periplus of Hanno), with disputed authenticity and date; the geographical reach of the voyage is much debated. The coordinates are those of Carthage, where it set out.

What it led to

  • ancient knowledge of the African Atlantic coast, passed on to Pliny and Ptolemy
  • Punic colonisation of Morocco (Thymiaterion, Cerne)
  • controversy over the southern limit of the voyage (Senegal, Sierra Leone or Cameroon)
