Gregory Benford's Sailing Bright Eternity has now been listed both as one of several sf titles incorporating "Eternity" and as one of many sea-space comparisons. That three word title is rich in meaning and connotation.
If space is metaphorically a sea, what are the bodies occupying it? Planets are a Pebble In The Sky (Asimov) or A Stone In Heaven (Anderson). Larger heavenly bodies are The Stars Like Dust (Asimov) or Galaxies Like Grains Of Sand (Aldiss). (Just think about that for a second.)
However, the galaxy can be a "...river..." (previous post), The Stars Are Also Fire (Anderson), ...And All The Stars A Stage (Blish).
(Blish also has the phrase "...the sands of the stars...," quoted in the previous post.)
We do not usually think of titles, especially of works by different authors, as forming a sequence or as presenting alternative perspectives on the universe. In fact, book titles are often used just as labels for the works to which they refer rather than as meaningful phrases in their own right. However, sf writers often need to use cosmological terminology and also of course to avoid repetition. Thus, some interesting although unintended sequences can emerge.
