The Dromon

Ferrebeekeeper has had the same group of topics for a long time, so it is time to experiment with some new ones.  Today’s topic—ancient ships—is not entirely new on this blog.  We have already written about various galleys and longships (including a Greek trireme, an ancient Egyptian reconstruction, and a Viking longboat), however today we concentrate on the greatest warship of the Byzantine navy, the mighty dromon.   The dromon was the mainstay of the Byzantine navy for seven centuries from the 5th century AD to the 12th century AD.  The galley was based on the ancient Roman liburnian, a sort of small galley used for patrols and raids by the Roman navy. Dromons were different from liburnians in that they abandoned underwater rams (which were in declining use in the Empire) for an above-the-water spur.  Additionally dromons featured a full deck, and they were rigged with lateen (triangular) sails by the age of Justinian.

The principal feature of the dromon, as with other ancient Mediterranean warships, were the banks of oars which propelled the ship in battle.  Earlier dromons of the sixth century were single-banked (“monoreme”) ships with 25 oars per side, however by the ninth century it seems that dromons were being built with 2 banks of oars divided by a deck.  The top bank held 25 rowers per side and the bottom could have had up to 35 which meant the ships were crewed b 120 rowing men.

Dromons were fearsomely outfitted with weapons.  In addition to their sharpened spike (which was used to sheer off the oars of rival boats) they had great companies of marines—armored soldiers who boarded enemy vessels to fight their crews by hand.  A grand spout on the prow was used to spray Greek fire, a sticky napalm-like flaming liquid which was extremely hard to douse (the exact nature of which has been lost to history).  Large dromons had wooden castles at fore and aft from which marksmen could fire bows, crossbows, or scorpions.

Dromons were the principal craft which the Byzantines used in their many wars against barbarian invaders like the Vandals and the Rus and then against successive Muslim dynasties hellbent on taking the empire.  These naval battles must have been horrifying and grand to watch.  Greek fire gave the Byzantines some advantage (although it was treacherous stuff) but eventually the ships would become entangled.  The marines would snatch up their shields from where they hung along the sides of the dromon and together with all the oarsmen (who were not slaves but fighters) would participate in brutal pitched battles.
