A Twelfth Century View of a Ship. (ca. 1150-60)
A low-relief carving in Tournai
stone, from the font
at Winchester Cathedral. It is part of the story of St Nicholas.
Note the rows of nails along the lands of the strakes of
planking. They mark this ship as being clinker built,
though the artist has not fully grasped the details. Note particularly, the rudder on the centre-line of the
vessel. It had replaced the earlier steering oar, used until this time. This is
among the earliest representations of such a rudder in a north-European ship so
the ships in which Hereward travelled will have been of the earlier sort.
It
is interesting to see that the animal head carving has been transferred from
the head of the sternpost to the head of the rudder stock. Some such
arrangement was necessary in order simply to permit the use of a tiller. The
artist was sufficiently at ease with the new technology to have noticed that.
According to the several views of ships in the Bayeux Tapestry,
steering with an oar on the starboard quarter of the ship was clearly still current
practice in the 1060s (Grape).
In the picture below, of the earlier ship, the man in the forward end is taking
soundings with a pole, as the vessel approaches a beach.
