The impression that a Viking fleet must have made under full sail can scarcely be imagined today, but a rhapsodizing monk at the monastery of St. Omer, France, tried his best to evoke the sailing of the royal Danish fleet in A.D. 1013:

"When at length they were all gathered, they went on board the towered ships...On one side lions molded in gold were to be seen on the ships, on the other birds on the tops of the masts indicated by their movements the winds as they blew, or dragons of various kinds poured fire from their nostrils...But why should I now dwell upon the sides of the ships, which were not only painted with ornate colors but were covered with gold and silver figures?...The blue water, smitten by many oars, might be seen foaming far and wide, and the sunlight, cast back in the gleam of metal, spread a double radiance in the air."
