Pentacle Drakar
The most famous ancient ships were undoubtedly the Viking's efficient warships, known as "dragon ships" or "drakkars".
They were long, graceful vessels, fast, reliable, and yet light enough to row or carry on warriors hands - if necessary. Drakkars were designed to enter shallow rivers and dock wherever needed. Such speed and mobility allowed the Vikings to take their enemies by such a cruel surprise.
The ancient craftsmen designed drakkars as a goal - to build a ship in such a way that, going on oars, it could carry shields on its sides.
The oars were not inserted into the oarlocks, but passed through special holes - rowing hatches.
For battle, ships usually converged on oars; if at the same time it was possible to keep shields on board (that is, if the ship was lined up so that the shields did not block the holes for the oars and did not interfere with rowing), they served as additional protection for the rowers until the very moment of hand-to-hand combat.
The most famous of the mythological drakkars are undoubtedly Skidbladnir and Naglfar.
The first one belongs to Freyr, and, according to legends, it can accommodate the entire army of Asgard, including all of the Einherias.
Naglfar, the second one, was created entirely from human nails - in the times of Ragnarok it will be freed from earthly captivity by a flood, and, under the leadership of laughing Loki, will sail out of Helheim for the last battle with the Aces.
