After the fall of the Eastern Roman Empire the struggle on the Mediterranean Sea was held between Byzantine and the Arab world. The dromon became the main type of ships at that time and besides, both opposing sides used them. She was a war ship who dismissed biremes and liburnas. Firstly the dromon was launched about the 6th century A. D. and was used in different variants up to the 12th century. We little know about this ship, however the Byzantine manuscript dated by the year of 850 contains an engraving with the dromon of that period. Her construction resembles that of the bireme with two rows of rowers. She had two masts with Latin sails on them. But the first vessels of such a type had only one row of rowers and they looked like a liburna with a single mast. Later on two- and three-masted dromons appeared. Their length was varied from 30 to 50 m, the width – from 6 to 7 m. There were helms on the stern – one at each side of a board. The ships had sharp forms and were sufficiently fast. The crew consisted of from 100 to 300 people depending on dimensions of a ship. There was another ship in Byzantine called heladion, but we know quite less about her than about the dromon. The dromon’s keel ended by an underwater ram just like for the bireme. The main weapons on the dromon were catapults, which threw fiery shells at a great distance. On the bow and the stern parts of the vessel there were raised decks for bowmen. Powerful and heavy catapults had a possibility to throw shells with the weight of 500 kg at the distance of 1 000 m. Dromons were also armed by light flame-throwers (syphonopho-rami), which flooded enemy ships by fluid burning mass (Greek fire) consisted of tar, sulphur and nitre dissolved in oil. At slight contact with water this fluid blazed up. Such a fire only flamed up in extinguishing by water and it was put out only by wine, vinegar or sand. The precise consistence of such a mixture as well as a construction of weapons did not come to us. Dromons were defended by metal armour against enemy’s rams.
Egyptian ship made of papyrus is one of the ancient in the world. Firstly it represented itself only a papyrus raft and to about 3500 year B.C. it became already a real ship. The ship was used only for navigation on the river Nile. Her bow and her stern were raised specially to pull her across shallows. But foreseeing the possibility to raise the bow and the stern higher with the help of ropes, Egyptians started their voyages at sea. The known expeditions of Tour Heyerdal on the papyrus rafts Ra-1 (1969) and Ra-2 (1970) showed that papyrus could stand two months of seafaring. Of course, Ra-1 had sunk earlier but it was due to great roughness at sea and the fault of the crew who did not pull the rigging steering the curve of the stern. On Ra-2 the stern was raised sufficiently from the very beginning of the seafaring. Ra-2 departed and in two months she reached Bridgetown, the capital of Barbados. Constructively Ra-2 was made of short papyrus bundles as they saturated less water. Bolivian Indians from the lake of Titikaka built Ra-2. From ancient times up to nowadays they navigate on such cane vessels calling them ‘totorus’.
Egyptian sailing ships were built by binding together papyrus bundles and the thickest of them were placed on the outer surface of the vessel. The sail was square. It was made of cloth or papyrus. It was hung on two yards, which were tied together to make them longer and which were fastened to the two-legged mast.
At moving downstream the Nile there was always a head wind and at upstream navigation there was a strong flow so the sail was useful. Rafts and vessels of such a type are used nowadays in the Eastern Africa, Persian Gulf and South America.
The images of Etruscan vessels are found on the tombstones of the central part of Italy (dated the 4th century B. C.). Resembling ancient Phoenician vessels by their forms these ships were differed by their sharper curve of posts and they had much in common with later vessels of North-European peoples. As in the Viking ships their oars passed through the holes in boards thus giving a possibility for more comfortable (lower) placement of rowers and for their defense by a high board. Short leather hoses closed slots between oars and a board. The vessel was steered by a single steering oar with a cross helm strengthened outside the starboard. The mast installed in the middle part of the ship carried a square sail with a yard. The upper band of planking was ornamented by a stylized image of a wave. The sternpost with two outside hanged shields was ended like a fish tail. The same shields were strengthened in the upper part of the stem and along the whole board. A figure in the form of a sheep head was installed on the bow part of the ship. It was a useful constructive element that defended the hull of the ship against the strike of an enemy’s ram. The fighting metal ram was installed at the waterline level and was strengthened to the keel beam. Wide, high boarded, with a big sagging Etruscan vessels obtained sufficient seaworthiness for navigation in the Mediterranean Sea.
It is commonly believed that Mu‘awiya Ibn Abi Sufyan was the first planner and establisher of the Islamic navy. A careful examination of primary sources reveals that the first Islamic naval expedition in history took place in AH 17/638 CE during the caliphate of ‘Umar Ibn al-Khattab and was led by al-‘Ala Ibn al-Hadrami, governor of Bahrain, against Persia; it ended with a trapped Islamic army nearby Istakhr. Three years later, in 20/641, with the permission of ‘Umar, ‘Alqama Ibn Mujazziz crossed the Red Sea toward Abyssinia. The expedition was disastrous, and only a few ships returned safely to their home port. In view of these facts, one may justifiably feel that the reluctance of ‘Umar Ibn al-Khattab to permit his generals to embark on naval adventures did not result from religious considerations but from his unsuccessful and disastrous attempt against Abyssinia. However, the establishment of the Islamic navy in the Mediterranean Sea occurred during the reign of Uthman Ibn ‘Affan. It was through the joint efforts of ‘Abd Allah Ibn Abi Sarh, governor of Egypt, and Mu‘awiya of Syria that the first maritime expedition on Cyprus in 28/648–649 was launched.
The Islamic expansions in the East and the West were not destructive. Muslim authorities not only preserved all dockyards, naval bases, and systems in the former Byzantine and Persian provinces, but they also founded new maritime installations—arsenals and naval centers—along their maritime possessions. Along the Syro-Palestinian coast were Tarsus, Laodicea, Tripoli, Beirut, Tyre, ‘Asqalan, and, most importantly, ‘Akka (Acre), from which the first Islamic naval expedition was launched against Cyprus; Egypt had Alexandria, Rosetta, Damietta, Tinnis, Babylon, and Clysma on the Red Sea. As for North Africa and Spain, their most important naval centers were Barqa, al-Mahdiyya, Tunis, Bougie, Ténès, Badis, Ceuta, Cádiz, Algeciras, Seville, Málaga, Almuñécar, Pechina/Almeria, Cartagena, Alicante, Denia, Valancia, and Tortosa. Likewise, they maintained and developed several naval centers in strategic Mediterranean islands, such as the Balearic Islands, Sicily, Crete, and Pantelleria. As a protective measure and until Muslims had acquired supremacy over the sea, the headquarters of their fleets were located in inland waters; the Egyptian navy was in Babylon, whereas the Andalusian one was in Seville.
Amir al-bahr (admiral) was the supreme commander of the maritime frontiers and naval forces. The duties of the construction of warships and the selection of appropriate materials—timber for keels, planking, masts, yards, oars, oakum, metals, skins, cables, pitch and tar, and other fittings—were laid upon him and a team of inspectors, who had to ensure that shipwrights observed technical standards and did not use inferior or inadequate raw materials. Every ship passed a comprehensive technical inspection while it was still in the yard and during the journey to avoid unpleasant consequences. Among the types of warships built in the arsenals for the fighting fleets in the eastern and western basins of the Islamic Mediterranean were dromon, fattash, ghurab, harraqa, jafn, jariya, qarib, qarqur, qishr, shalandi, shini, tarida, and zawraq.
The responsibility of recruiting highly skilled sailors, patient artisans, brave warriors, alert spies, and physicians rested with the admiral and his chief commanders. Papyri from early Islamic Egypt show that the method of recruitment of sailors for the raiding fleets was compulsory; sailors were drawn from all provinces and included various classes of the population. In case of reluctance or fugitiveness, the local authorities had to pay the wages of men hired from another place. As for the fighting men, they were Arab emigrants and mawalis who settled in the Levantine, Egyptian, and North African frontiers. Only experienced crews and warriors with high morals who were faithful, professional, and fearless in the face of the enemy were taken onboard. Supplies for the ships’ human element included bread, butter, wine, oil, and salt.
Only a few Arabic manuals dealing with Islamic naval warfare have survived. Ibn Mankali’s handbooks, Al-Ahkam al-Mulukiyya wal-Dawabit al- Namusiyya fi Fann al-Qital fi al-Bahr and Al-Adilla al-Rasmiyya fi al-Ta‘abi al-Harbiyya, give great detail about naval preparedness and tactics. Because Islamic warships could be attacked with all kinds of weapons, their commanders were instructed to carry a large supply of spears, swords, crossbows and arrows, stones and catapults, venomous creatures sealed up in earthenware jars, and combustibles and Greek fire. Ibn Mankali describes how to be prepared against enemies, addressing such things as the following: exercises; prayers offered and speeches delivered before the actual combat; time, place, and disposition of enemy; strategic tactics and arrangement of warships; disposition of the flagship; and the flags to be used during the maritime battle for signaling purposes.

Land troops were supported by the Roman navy which was part of the army and not a separate service. Standing fleets of warships (for fighting) and merchantmen (for supply and transport of troops) were based throughout the empire. Individual squadrons were commanded by praefecti. In the west the major fleet was based at Ravenna, though there were other fleets in Italy, Gaul, Africa and Britain. In the east Constantinople became the major fleet base, while other smaller fleets were based in Egypt, Antioch and the Crete–Rhodes region. As part of the army naval expeditions were commanded by generals. In 324 Constantine’s fleet was commanded by his son Crispus, while Licinius’ was under an otherwise unknown Amandus. Later in the sixth century Belisarius reconquered Africa as the magister militum per Orientem.
Although fleets made a significant contribution to Roman military power, through defence of the Rhine and Danube frontiers by river flotillas and logistical support, there were very few campaigns which could be characterized as naval, primarily because Roman enemies rarely possessed significant fleets of their own. By far the most important naval encounters occurred in civil wars, the defeat of Licinius in the Bosphorus in 324 and the failure of Vitalian’s attempt on Constantinople in 515 when Greek fire was used to destroy his ships (Malalas 16.6 Thurn=403.5–406.8Dindorf ). In the 250s and 260s Gothic groups north of the Black Sea gained control of local fleets and rapidly became proficient at raiding, but their motley collection of fishing vessels, merchantmen, rafts and naval boats was always vulnerable to challenge by a proper fleet. Carausius and Allectus in Britain were a more formidable threat, since they had taken over the imperial Saxon shore fleet, and their suppression by Constantius in 293– 6 entailed a substantial naval expedition (Pan. Lat. 8.11–19). The Vandal capture of Carthage gave them control of Roman shipping and led to the first serious challenge to imperial domination of the Mediterranean since the PunicWars of the Republic, but their main activity was ravaging; even the massive expeditions dispatched from Constantinople in 468 and 533 passed off without confrontation at sea, the former being disrupted by fire ships at Syracuse and the latter arriving when the Vandal ships were busy off Sardinia. In the east it was feared that Persian access to the Black Sea would permit them to develop a fleet and threaten Constantinople (Procop. Wars 2.28.23), but when the Persians did eventually capture Phoenicia and Egypt in the seventh century they did not exploit what maritime resources fell into their hands: at Constantinople in 626 the Persians relied on Slav canoes to ferry them across the Bosphorus (Chron. Pasch. 722.14–723.12). The Slavs were effective raiders, but their light ships were no match for proper Roman vessels, as the engagement in the Golden Horn in 626 demonstrated (Theodore Syncellus 311.7–312.5; Georg. Pis. Bellum Avaricum 441–74). It was left to the Arabs to create a powerful fleet, in spite of the reluctance of the Caliph ‘Umar and their inexperience of maritime matters; the development was as striking as the emergence of the Roman navy during the First Punic War.
