I’ve you’re reading articles about Lewis, you’ll quite often see this picture of Lewis and a number of other men sitting on a short wall:
I recently saw this article from the Sydney Morning Herald which included a cropped version of this picture, identifying the men, from left-to-right as J.R.R. Tolkien, Owen Barfield, Charles Williams and C.S. Lewis. However, this is incorrect!
The men in the above picture are Commander James Dundas-Grant, Colin Hardie, Dr. Robert E. Havard, C.S. Lewis, and Peter Havard. They are sitting on the Thames River embankment parapet wall at The Trout pub. Behind them (out of shot) is the old Chinese style wooden bridge, leading over to the island which had a stone lion statue on it.
