here to Lancaster quay so I thought that it was time for a picture. Lancaster Priory Church can be seen in the background. A fantasy or sf reader can imagine walking along the quay into Lancaster's maritime past which is remembered in a museum on the quay.
Poul Anderson coined the evocative phrase, peregrinator temporis, time traveler. Alan Moore goes further and refers to "...the temporal pedestrians..." (Jerusalem, London, 2016, p. 982)
Moore's ambulatory time travelers find whales that have grown legs and adapted back to land. This reminds us of "land-whales" mentioned by Anderson! (I can find obscure cross-connections anywhere if I am determined enough.)
