 A remembrance of Sigtrygg 's reign during these years is preserved in the late medieval Icelandic Saga of Gunnlaug Serpent 's Tongue . Only fragments survive of the verses in the <unk> , a <unk> composed by the skald Gunnlaug <unk> while visiting Sigtrygg 's court . The verses praise Sigtrygg for his royal ancestry , and describe Dublin as a busy , thriving port . Archaeological excavations of ships , gold , clothing , and pieces for games from around this time seem to confirm the description . According to the prose , Sigtrygg considered rewarding the poet with ships and gold , but instead granted him a new suit of clothes .
