 This proposal is part of an archaeological survey of selected areas of the Red 
Sea coast and islands with a sailboat to identify ancient ports, anchorages and 
shipwrecks especially from the Ptolemaic, Roman and early Byzantine periods 
(viz. the 3rd c. BCE until the 7th c. CE). This will include both land and 
underwater investigations at stops along the ancient maritime routes linking the 
northern Red Sea with the Indian Ocean, in the countries of the Kingdom of Saudi 
Arabia, Sudan, Eritrea, Djibouti and Yemen.
This proposal is part of an archaeological survey of selected areas of the Red 
Sea coast and islands with a sailboat to identify ancient ports, anchorages and

northern Red Sea with the Indian Ocean, in the countries of the Kingdom of Saudi 
Arabia, Sudan, Eritrea, Djibouti and Yemen. 
The purpose is to locate some of the ancient ports and settlements from north to 
south for possible future detailed survey and/or excavation. These would include 
examination of a number of sites which may be associated with the ancient ports 
of Charmuthas, Heptaphreata, Bulicas, Leuke Kome, Athrula and Asca along the 
Arabian coast; Cleopatra’s harbor, Ptolemais Theron, Panchrisos, Berenice near 
Saba, The Altars of Konôn, the Grove of Eumedes and other ancient coastal cities 
along the African coast. Such a project has never before been undertaken. We 
have discussed this endeavor with and received initial verbal approval from the 
Sudanese authorities and the interest of the Saudi Geological Survey‘s 
Geoheritage Program. We are now approaching authorities in Eritrea, Djibouti and 
Yemen to seek their approval for the project. 
The expedition for the study of this maritime route will be conducted from a 
sailboat, which will recreate conditions of ancient merchant ships in coastal 
navigation, and facilitate access to many remote locations that would be 
difficult to approach from land. 
Objectives 
By compiling and studying detailed satellite imagery and combining this with 
reading the ancient literary sources, Nautical charts, and sparse archeological 
literature published on this part of the Red sea, we will be able to select 
among the GPS positions of coastal remains that we believe are most likely 
ancient settlements linked with the maritime trade route, findings that have not 
been previously published. 
We will anchor the sailboat at moorings with ruins that we have already briefly 
visited and near the GPS positions that we propose to identify (see list below), 
and consult with local residents and fishermen to identify ancient remains. The 
discoveries will be documented precisely using GPS positioning, photography and, 
where feasible, the drawing of more detailed, measured architectural plans. This 
data will form the basis for the publication of a gazetteer which can be used in 
possible, more detailed follow-up investigations and excavations.
