Potential Ancient Harbours

_________________________________________________________________

Summary

Over 4400 ancient coastal settlements have been identified so far. It may be accepted that all of them had some kind of boat landing or shelter. From a nautical point of view, many of these sites are not considered very good for sheltering modern yachts, but were nevertheless used in ancient times. Conversely, would you believe that a shelter that is considered today as “excellent” from a nautical point of view would not have been used in ancient times, at least as a bad weather refuge shelter?

If such a place, in addition, provided fresh water and food, it could become more than a simple refuge. If it also had some “hinterland” providing trade opportunities, it could become a bigger city with sufficient resources to build specific port structures like breakwaters and quays.
The aim of the present study is to list “Potential Ancient Harbours” from a comparison of “excellent” modern shelters and recognised ancient coastal settlements. The result is a list of over 200 places that might be further considered by historians and archaeologists to find out if they were indeed ancient settlements.

Ancient harbours

A harbour is a place where ships can seek shelter. The concept of ‘shelter’ has to include anchorages, landing places on beaches, and ports including structures such as access channels, breakwaters, jetties, landing stages, quays, warehouses for storing commodities and equipment, shipsheds and slipways. Shelters of interest for this catalogue include all places which may have been used by seafarers sailing over long distances.
During military expeditions, 200 people had to be fed on board triremes. It was impossible for ship masters to fill their ships with tons of food. In the absence of ports, ship pilots had to find beaches with a degree of shelter where drinking water could be found, and river estuaries could provide both.
Commercial ships obviously preferred sheltered creeks, possibly with some kind of jetty, as their ships were too heavy to be pulled on the beach. Seafarers obviously preferred shelters with clear landmarks on shore (such as a typical mountain) and many shelters were needed, as seafarers often followed the coast, using safe shelters to stop overnight and escape bad weather. Even though they could sail 50 to 100 nautical miles in a day, it was important to know where they could find safe shelter within two to three hours of navigation, i.e. only approx. 10 miles.
Many of these sheltered creeks still exist today, but large changes have sometimes occurred:

  • crustal movements (e.g. Alexandria, Crete) which explain why ancient ports are sometimes buried under the modern ports;
  • a eustatic sea level rise of around 0.50 m over the past 2000 years (estimations range from nil to more than 1.50 m, see Nic Flemming’s work);
  • seismic events inducing tsunamis which devastated adjacent coastal plains (e.g. Crane/Agrostoli);
  • river estuaries usually tend to silt up, as rivers carry most of the materials that create beaches, and this explains why some ancient ports are now so far from the sea (e.g. Portus at Fiumicino, Ephesus) or have simply filled up with sand (e.g. Leptis Magna);
  • in some large cities, the ‘old port’ has been reclaimed to create a new waterfront area (e.g. Marseille);
  • beaches are subject to sedimentation and erosion by wave action, and the latter explains why some ancient ports were lost to the sea (e.g. in Tunisia).

It should be noted also that ports mentioned here have been collected from texts of various dates ranging from 500 BC (except for Homer) and 500 AD (with a few exceptions), that is 1000 years. The various authors have not seen the same things … and some authors have just repeated what others wrote before them!

The author of the present work compiled a list of ancient ports and harbours with latitude/longitude positioning, based on 66 ancient authors and some modern authors, e.g. Karl Lehmann-Hartleben (1923), Honor Frost (1963), David Blackman (1982 & 2014), Talbert’s Barrington Atlas (2000), Nic Flemming (1986), Getzel Cohen (1995 & 2006), Micha Tiverios (2008), Helen Dawson (2013), Gordieiev (2015) and some up to date web sites (http://pleiades.stoa.org/ and http://dare.ht.lu.se/ ).
This Catalogue of Ancient Ports contains over 4000 places.
It can be viewed on: Catalogue of Ancient Ports.

Modern shelters

Modern yachtsmen use sailing guides, “Pilots”, for each area. These guides provide information on sailing routes, waypoints, services to be found in marinas, etc. They sometimes also rate the quality of the shelter:

  • A: excellent,
  • B: good with prevailing winds,
  • C: reasonable shelter but uncomfortable and sometimes dangerous,
  • O: in calm weather only.

Shelters are defined for modern sailing ships with modern sails and some “A-shelters” might prove not that good for ancient ships with square sails. An excellent A-shelter provides all-round protection from wind, waves and currents, from all directions and at all times. This kind of protection from offshore waves is usually found inside bays with a narrow entrance and complex shape such as a “dog-leg”. Protection from wind is important also and usually depends on the land topography surrounding the shelter.

The work sequence was to list A-shelters and to check if each of them was or not recognised as one of the ancient harbours mentioned on the Catalogue of Ancient Ports. Therefore the 14 modern nautical guides, or “pilots” listed in the references hereafter have been searched. They contain over 4000 shelters, anchorages, marinas and commercial ports. Around 25% of them are excellent shelters. After comparing each of them with the Catalogue of Ancient Ports, a list of 210 potential harbours was obtained for shelters that are not yet recognised as ancient harbours, but are good candidates from a nautical point of view.

This list is summarised in the table below, grouping the numbers of Potential Ancient Harbours (PAH) for each area.

COUNTRY PAH
Spain & Portugal 5
Baleares islands 19
France West & South & Corsica 4
Italy, Sicily, Sardinia, other islands and Malta 12
Adriatic Sea 53
Greece & Crete 27
Black Sea 2
Turkey West & South 9
Red Sea & Oman & Somalia 78
Levant, Cyprus & North Africa 2
Total 211

The maps hereafter show that quite a lot of Potential Ancient Harbours are found in Greece, scattered on the mainland and on the islands. Concentrations of Potential Ancient Harbours are found in Croatia, on the Baleares islands and NE Sardinia. The Red Sea provides the largest number of Potential Ancient Harbours, but they are scattered all over the area, with a concentration of “marsas” in Northern Sudan.

Location of potential harbours, shelters & ports

Some additional potential ancient ports

Everybody knows that a coral reef borders the Red Sea on almost its entire length. It is known also that the coral reef hates fresh water, polluted water and sediment and that it therefore is interrupted in places where large ‘wadis’ have their outlet into the sea. Such discontinuities of the reef provide deep water coves that can be used as shelters for ships. As a matter of fact, water is very deep (over 10 m) and the reef features a kind of vertical underwater cliff. I had an opportunity to swim in such a place in the nineties with my friend Xavier Bohl from Port Grimaud when we were asked to design a marina in a place now called Port Ghalib, and I confirm that it is an impressive swim as one cannot see the seabed although the water is crystal clean. Such a deep water cove is obviously not for anchorage, but the little beach inside the cove is suited for beaching.

The Google Earth view below shows the Marsa Gawasis cove as an interruption of the coral reef, and wadi Gawasis flowing into the sea.

The main point here is that

this interruption of the reef and the resulting cove
has been there for 4000 years.

Until recently, I thought wadis were wandering around and present coves were not ancient. However, I changed my mind when looking at Marsa Gawasis where recent archaeological finds show that this cove was used as a sea port in very ancient times 4000 years ago (Bard & Fattovich, 2007[1]; Tallet, 2015[2]).

Other similar places where this can be seen are Wadi Safaga located 9 km North of Wadi Gawasis, a place possibly called Quei located 26 km South of Wadi Gawasis, Hamrawein port (possibly ancient Arsinoe Troglodytika), Quseir al-Qadim (ancient Myos Hormos), Marsa Dabr, Marsa Nakari (ancient Nechesia?).

This new insight may help to identify other ‘potential ancient harbours’. This does of course not mean that an ancient port will be found in each present cove on the Red Sea coast, but it may be worth listing them in order to have a closer look for archaeological remains in these places in the future. Note that many of these coves are used today for holiday resorts and diving centres which may be a sign of good shelter. Here is the list for the stretch between Hurghada and Ras Banas (400 km). This stretch was chosen because it is the most likely area where ships would stop fighting against the northern wind when returning from their trip to the Land of Punt, and would unload their precious cargo to continue over land to the Nile river.

Conclusions

The aim of this study is not to provide a comprehensive list of yet unknown Potential Ancient Harbours based on rational and scientific deductions, but rather to list places that might be further investigated by historians and archaeologists. The somewhat intuitive methods used here do not give any proof, but just an indication of Potential Ancient Harbours.

Some areas show few Potential Ancient Harbours and this may be due to:

  • ancient authors providing a comprehensive description of the coast (e.g. Arrian in the Black Sea);
  • comprehensive modern archaeological surveys (e.g. in France, Italy, Spain, Tunisia); hence, many of today’s excellent shelters are recognised ancient harbours (e.g. in France, Italy, Spain);
  • many of today’s excellent shelters are modern marinas just added to a coastline without any good natural shelter and do not qualify as Potential Ancient Harbours (e.g. in France, Italy, Spain);
  • some nautical guides did not survey the smaller anchorages (e.g. North Africa).

Without insult to the modern authors of the nautical guides, it can be said that the ancient Stadiasmus includes more places than the modern pilot of the North African coast between Carthage and Alexandria! The same holds for Arrian’s periplus of the Black Sea.
Conversely, some areas show many potential ancient harbours. This is probably due to a reversed combination of the above factors, e.g. in the Red Sea, Croatia where ancient sources are inaccurate, if any, and modern pilots are quite detailed.

The Catalogue of Ancient Ports & Harbours tries to be exhaustive, but is most probably not. Hence, some Potential Ancient Harbours listed here may be recognised by some expert as ancient harbours already known to him and the present author will be delighted to hear about that in order to remove such places from the list of “potential” ancient harbours. However, large parts of the listed Potential Ancient Harbours are probably real newcomers and will definitely require more attention from historians and archaeologists to find out if they were indeed ancient settlements.

Some of these places may not show a single sign of ancient presence at the anchorage or on land because erosion may have taken away all remains; they will therefore remain “potential” ancient harbours. Hopefully, other places will provide more evidence of ancient human presence (amphorae, stone anchors, ballast stones, etc.) even if this evidence may be difficult to find as it may be under water and buried under thick layers of sediment.

Even more optimistic, the list of Potential Ancient Harbours might help historians re-interpreting ancient “Periploi” and Ptolemy’s places in the Red Sea …
