[1-6]: The coastal landscape around Grimsby is characterised by both mud-flats and salt-marshes and the town itself was virtually an island with only one road into it at the end of the Middle Ages (Gillett 1970, 1). The st. appears to describe the Norwegians’ regular journey across the mud-flats to the town from their mooring-place in the haven during their stay. The sea-kenning mýrar ms ‘marshes of the gull’ is ironic since by then the sailors have left the marshes behind and the contrast is underlined by the two descriptors in megin- ‘mightily’, which contrast the grimness of their weeks in Grimsby with their pleasure at setting off for home.
