The Icelandic historian Trausti Einarsson (1987) has discovered that this was a reference to twenty foreign ships fishing off Iceland, as the English and other nations were fishing for cod there by the early 15th century.
Islandski povjesničar Trausti Einarsson (1987.) je otkrio da je to bio spomen dvadesetak stranih brodova ribolovaca kod Islandu, budući da su Englezi i ostali narodi lovili bakalar tamo početkom 15. stoljeća.
