I read the article as providing background for how the scene on the boatdeck was 'reconstructed' (the Sphere's description) from an eyewitness account. The image is a popular one, but until Senan's article, many people might not have been aware that it was based on more than Matania's instincts and the popular press. What particularly intrigued me was the claim of specific comments on the part of the witness, e.g. 'No, the man stood here - a foot more to the right.'
Of course, as Senan well knows, eyewitnesses aren't infallible. This is not an objective account, but rather reliant upon the memory of someone who was there, further filtered through the medium of artistic interpretation (however hard Matania strove for accuracy).
I'll have to ask the amateur astronomer in the family about the position of Orion that night! If it was innacurately depicted as being in the wrong position at the wrong time, we don't know whether that was deliberate artistic license or the result of an innacurate observation from the eyewitness (albeit perhaps not quite as dramatic as the 'moonlight' some witnesses thought they saw). It's an interesting point, though, and one perhaps only Matania could answer accurately - perhaps he should have just settled for splashed paint rather than attempt to accurately depict the scene with a survivor to coach him!
The article certainly made me appreciate and look with new eyes upon an image that had become worn through over-familiarity. Now I have to wonder about the shoe on the deck, placed there by the stewards memory. Great article, Senan!
