Marquadt uses many technical terms without explaining them, so when I borrowed through my local library two articles he had written earlier about the ship, I was delighted to find they were much easier to understand. In the first7 he explains why Thomas Luny's well known painting "The Earl of Pembroke leaving Whitby Harbour" may not be an accurate representation. He writes "Luny was eight years old when the event occurred. His first paintings date from 1777, two years after the Endeavour had been sold out of service. It may be assumed that the idea for this painting surfaced when news of Cook's death reached England early in 1780. What Luny brought to his canvas was not an authentic portrait of the Earl of Pembroke but the portrait of an anonymous eighteenth century collier which, for patriotic and commercial reason, the artist labelled Earl of Pembroke."
He goes on to say "Modern artists do not have Luny's choice of near-contemporary craft to guide them in depicting the Endeavour, but they can refer to the original plans or to a model for their conceptualisation. However, the contemporary plans are not very explicit about the stern, hatches are shown only as empty spaces, and many minor details are omitted. Painters and model makers alike either ignore what the plans do not show, or give rein to their imagination even where research into other contemporary sources would provide a more satisfactory answer. For example, until recently the Endeavour was generally thought to have had no stern decoration at all. Some interpretations show the ship's name on the upper counter even though research would have shown that this fashion did not come in for the Royal Navy until 1772, and lasted only until the beginning of the war against revolutionary France."
In his second article8, Marquadt explains what drove him to his research. "I planned to build a model (which has not eventuated for lack of time) and tried to tie up a few loose ends. Having looked at the original draughts, at a multitude of modern kit versions, artists' impressions, and a number of museum models, I could not believe what I saw... I found a whole fleet of contrasting models". In this article he compares and contrasts the two models built at the National Maritime Museum, Greenwich and presented by Her Majesty to the Queen to the Australian and New Zealand Nations, and one built for the National Maritime Museum by Robert Lightley. The last one is well described and illustrated by the modeller in another article9.
One point that Marquadt deals with is the description of the Endeavour as "a Cat-built Bark" by the Navy Board in 1768, "a bluff-headed bark" by Beaglehole, and "a sort of ship-rigged cat" by Villiers. He concludes that she was a "cat-rigged bark".
