The Erythraean Sea (Greek: Ερυθρά Θάλασσα, Erythra Thalassa; "Red Sea") is the name in ancient cartography for a body of water located between the Horn of Africa and the Arabian peninsula. This appellation may have derived from the seasonal blooms of the red-coloured Trichodesmium erythraeum near the water's surface.[1]

In the third century, Flavius Philostratus made this comment: "And they say that the sea called Erythra or "red" is of a deep blue colour, but that it was so named, as I said before, from a King Erythras, who gave his own name to the sea in question." [2]

The name "Erythraean Sea" has been or is still used for the following places:

  • In the opening sentences of Herodotus's history, written in the 5th century BC, he refers to the Phoenicians having come originally from the Erythraean Sea.
  • In the Periplus of the Erythraean Sea, written in the 1st century AD, as well as in some ancient maps, the name of the sea refers to the whole area of the northwestern Indian Ocean, including the Arabian Sea.[3]
  • In centuries past, the name "Erythraean Sea" was applied by cartographers to the NW part of the Indian Ocean, mainly the area around Socotra, between Cape Guardafui and the coast of Hadhramaut. This appellation has now become obsolete and the name Gulf of Aden is presently used, although for a smaller area. In maps where the NW Indian Ocean is named thus, the Red Sea appears as "Arabian Gulf".
  • The name "Erythraean Sea" was used as well to refer to some gulfs attached to the Indian Ocean, specifically, the Persian Gulf[4]
  • As a name for the Red Sea, especially after the 19th century. The modern country of Eritrea was named after this ancient Greek name.
  • Since 1895, the name has also been applied to a large dusky region on the surface of planet Mars, known as Mare Erythraeum.
