In this volume Professor Sen McGrail introduces the reader to a relatively new branch of Archaeology the study of water transport how early rafts, boats and ships were built and used. Concepts, such as boatbuilding traditions, ship stability and navigation without instruments, are first described. Archaeological research is then discussed, including sea levels in earlier times, how to distinguish the vestigial remains of a cargo vessel from those of a fighting craft; and the difference between a boat and a ship.Chapters 2 and 3, the heart of the text, deal with the early water transport of the Mediterranean and Atlantic Europe, from the Stone Age to Medieval times. Each chapter includes a description of the region's maritime geography and an exposition of its boat-building traditions. The third element is a discussion of the propulsion, the steering and the navigation of these early vessels.The sparse, often jumbled, remains of excavated vessels have to be interpreted, a process that is assisted by consideration of early descriptions and illustrations. Studies of the way traditional builders of wooden boats ply their trade today are also a great help. Experimental boat archaeology is still at an early stage but, when undertaken rigorously, it can reveal aspects of the vessel's capabilities. Such information is used in this volume to further our understanding of data from boat and ship excavations, and to present as coherent, comprehensive and accurate a picture as is now possible, of early European boatbuilding and use.

CHAPTER 1

Egypt

The Greek historian Herodotus described Egypt as “the gift of the River Nile” since, without the fertility annually brought down this river and deposited as rich alluvium, Egyptian civilisation would not have existed. Moreover, the Nile may be said to have been responsible for Egypt’s nautical development since it was the principle means of communication. In essence, Egypt was, and is, a narrow stretch of cultivable land on either side of the Nile stretching northwards from the first cataract, a natural barrier south of Aswan, to Cairo where the vast delta lands began (Fig.1.1).

This delta region formed the greater part of what was known as Lower Egypt where, in Pharaonic times, there were three principal Nile channels: Amun/Canopic to the west; Ptah/Sebennytic flowing north; and Pre/Pelusiac to the east. The river flow slowed within the delta and much of the silt it carried was deposited on the land, thereby increasing fertility. Nevertheless, the discharge into the Mediterranean could still be recognised out to a distance of ‘a day’s sail’ (about seventy nautical miles) from the coast, where silt could be picked up on a sounding lead.

Within this exceptionally fertile valley, the technological achievements of Neolithic people led to a Bronze Age civilisation that rivalled that in Mesopotamia. The Nile was not only the ultimate source of Egypt’s prosperity, but also became the principal ‘highway’ of the land. Mesopotamia was similarly dependant on rivers, but Egypt had the advantage that the Nile flowed northwards, against the generally predominant northerly wind: sail could be used to travel upstream, rather than towing as in Mesopotamia. In Egypt the phrase, ‘to go north/downstream’, was represented hieroglyphically by a boat without a sail; ‘to go south/upstream‘, by a boat with a sail. Down the Nile, Egypt had direct access to the Mediterranean, especially to the Levant; up the Nile, then eastwards, through the eastern desert via the Wadi Hammamat (a dry river bed), led to Myos Hormos/Qusayr on the Red Sea coast, thence to Arabia and eastern Africa (Fig.1.1).

In Neolithic times, papyrus reed was used in rope-making and to bind bundle rafts. Flint, also indigenous, was used to make tools. Subsequently, copper from the eastern desert (supplemented by supplies from Cyprus) and tin imported from Asia were used to make bronze tools. Egyptian trees, such as the Sycamore fig, the date palm and tamarisk, produced planks that were less than 6 m in length. This led to the import of Lebanese cedar which was available in lengths greater than 20 m and was easier to work.

WATER TRANSPORT.

The evidence for Egyptian water transport includes not only excavated boats but also representations and descriptions of boats ranging from the Neolithic (5000 BC), through the Dynastic periods (3100–332 BC), and on into Graeco-Roman times at the end of which, in 30 BC, Egypt became a Roman province.

Non-plank craft

Rafts with their buoyancy derived from ceramic pots, from gourds or from reed bundles were used on the Nile and in its wide-spreading delta channels in the seventeenth century AD and continued in use into recent times. This suggests strong roots, possibly as far back as the pre-Pharaonic times. Indeed, there are several depictions of what may well be reed bundle rafts propelled by paddles, from the later years of the Pre-Pharaonic period (before 3100 BC). A detailed, though fragmentary, depiction of what is probably a boat-shaped bundle raft is on a fourth Millennium BC linen cloth from a grave at El Gebelein in Upper Egypt (Fig.1.2): a helmsman and several forward-facing crew are shown plying paddles. Innumerable depictions of similar rafts, on pottery dated around 3200 BC, have also been excavated.

From c. 3100 BC, in the proto-Dynastic period, a distinctively shaped hull with high, near-vertical ends is depicted on an ivory knife handle from Gebel el Arak (Fig.1.3). On the same handle there are similar vessels but with curved hulls that probably represent bundle rafts. Depictions of both types have been noted among petroglyphs on the Wadi Hammamat route through the eastern desert from Qusayr (Myos Hormos) on the Red Sea coast to Coptus on the Nile.

Although plank boats predominate in the iconographic and documentary evidence for water transport throughout Pharaonic times, rafts – especially those of papyrus bundles – continued to be noted. In Classical times, Strabo (17.1.4) mentioned individual large pots used as boats, and collections of smaller, sealed pots were linked together to give extra buoyancy to a light timber framework. Bundle rafts were also extensively used in the Delta marshlands of ancient Egypt when hunting, fishing and fowling. In the eighth century BC, Isaiah (18.1.2) noted that Egyptian envoys travelled to the Levant in papyrus-bundle rafts, and Pliny (NH 13.22.71-3) reported their use in his day as Nile ferries.

Planked vessels 3100–343 BC

A feature of boats and ships excavated from Egyptian sites is the use of ‘draw-tongue’ or ‘mortise and tenon’ joints as plank fastenings. The tenons in those early Egyptian boats were unlocked and were held within their mortices by an interference fit. In the earliest-known, but of later date, eastern Mediterranean vessels, tenons were locked in position by a trans-piercing treenail thus producing a stronger hull. This method of locking tenons was also known to the Egyptians: indeed, some were used in the superstructure of the Cheops ship (see below), but not in the hull. Dr Cheryl Ward has argued that this practice of not locking tenons persisted in Egypt because vessels, built on the Nile, but destined for use in the Red Sea, had to be dismantled so that they could be transported overland along the Wadi Hammamat to the coast where they were re-assembled. Such dismantling would have been impracticable if tenons had been locked.

Illustrations and models from Egyptian tombs can readily be found depicting just about every conceivable building action, and every operational use of a boat or raft. For example, see Fig. 1.4 in which a man uses his foot to tighten the bindings of a reed bundle raft. Furthermore, boatbuilding scenes depicted in the Fourth Dynasty chamber of Rahotep at Medum, the Fifth Dynasty mastaba of Ti (Fig.1.5) and the rock tomb of Nefer (both the latter at Saqqara), and in the Sixth Dynasty tomb of Mereraka, include illustrations of the following techniques:

• logs sawn into planks

• planks trimmed with axes and finished with adzes.

• symmetry ensured by setting a line from end to end of the boat

• mortises fashioned with chisel and hammer

• strakes pounded down onto tenons protruding from the strake below

• strakes fitted and aligned: the master shipwright checking the alignment with a ruler and plumb bob.

Other depictions in Nefer’s tomb show a hogging hawser, led over vertical crutches along the centreline, from bow to stern, to pre-stress the planking against forces experienced when afloat, thus ensuring watertight integrity. Other early Egyptian seagoing ships (for example, those on a relief in Sahure’s Fifth Dynasty burial temple at Abuir) are depicted with girdles at bow and stern, as well as a hogging hawser. By the reign of Ramesses III (1198–1166 BC) girdles and hawsers are no longer shown (for example, in depictions of Ramesses’ third, and decisive, sea battle against the invading ‘Sea People’). It seems likely that, by that time, Egyptian shipbuilders could dispense with such reinforcements because they now used locked mortise and tenon joints to fasten planking together.

Other innovations shown in these twelfth century BC depictions include: through crossbeams; a deck along the middle line of ships on which marines could stand in between the two files of oarsmen; oars plied through ports in the top strake; and a fighting top/lookout at the masthead. There was also a significant change in the rigging: the boom at the foot of the sail was replaced by brails. A loose-footed sail increased the master’s ability to achieve optimum sail shape, and brails allowed him to match sail area to increasing wind strengths by hoisting the foot of the sail up towards the yard. Differential brailing, if it were undertaken, could have led to improved windward performance under sail.

The Cheops ship

In 1954, the dismantled elements of a royal ship, dated to about 2650 BC, were recovered from an underground chamber at Giza, near the pyramid of Cheops (Khufu). This vessel is the oldest, near-complete, planked vessel in the world. After almost thirty years of research on, and re-assembly of, those remains Hag Ahmed Youssef Moustafa, of the Egyptian Antiquities Service, produced an impressive vessel measuring 43.4 x 5.9 x 1.8 m, the bow rising to 6 m and the stern to 7.5 m: she is now displayed in a museum in the vicinity of the Cheops pyramid (Fig.1.6). The size and complexity of this venerable vessel indicate that, by then, Egyptians had probably been able to build seagoing planked vessels for some considerable time, possibly as early as 3000 BC when a range of woodworking tools were used by them in other trades: axes, adzes, chisels, pulling saws, mallets, wedges, bradawls, sandstone rubbers, squares, levels and rulers.

The Cheops ship was built plank-first, with the cedar planking being positioned and fastened together in five different ways:

• Projections from plank edges enmeshed with indentations on adjoining planks.

• Wooden treenails across plank seams

• Unlocked mortise and tenon joints across seams.

• Widely-spaced, individual lashings of halfa grass across seams

• Transverse sewing from sheer to sheer: sewing holes within the plank thickness ensured that stitches were not exposed outboard and therefore would not be damaged when the ship was berthed (Fig.1.7).

1.7. The interior of the Cheops ship with temporary fastenings.

During this vessel’s working life, these features and fastenings would not only have resisted the tendency of adjacent planks to slide relative to one another (a movement induced by sheering stresses created when afloat) but also would have facilitated re-locating planking when fastenings were renewed, probably annually.

After the Egyptian shipwrights had fastened the planking together, the shell of the hull was stabilised by sixteen huge floor timbers lashed to the planking and by crossbeams let into the top strake. A massive, carling timber, supported by stanchions, was then positioned centrally on the crossbeams and lashed to them, thereby reinforcing the whole structure longitudinally.

Other buried vessels

Other Egyptian planked vessels, older than the Cheops ship, have been found, but appear not to have survived in such good order. The ritual of burying boats in association with the funeral of a pharaoh seems to have begun during the First Dynasty (3100–2890 BC) and continued sporadically until the Fifth Dynasty (c. 2345 BC), with an ‘outrider’ of five boats buried in Senusret (Sesostris) III’s burial enclosure in c. 1850 BC, some 500 years after the Old Kingdom use of such ritual burials.

In 1947, nineteen boat pits, thought to be of first dynasty date, were excavated at Helwan, and, in 1954, six were encountered at Saqqara. Although boat remains were noted, nothing seems to have survived from either excavation, and the subsequent publications tell us almost nothing about the boats. In 1991, a group of fourteen planked boats were exposed at Abydos, to the west of the Nile, some 250 miles upstream from Cairo. These boats had been buried within brick ‘coffins’ in a second-dynasty (2890–2686 BC) funerary enclosure. The planking of these flat-bottomed boats had been fastened together by transverse sewing across the bottom and sides of each boat, as in the Cheops ship.
