From swerve of shore to bend of bay

If "Eve and Adam's" is taken as equal to "even atoms" in the Epicurean sense, the word "swerve" has a special meaning; it refers to what Lucretius calls the "clinamen", or the "swerve" ever so slightly off of a true plumb line as atoms fall perpetually downward through the void; this is the principle that animates the universe. Hence "swerve of shore" = "swerve off sure" (sure = true, straight, plumb). For more, see the poem De Rerum Natura (On the Universe) by the Roman poet T. Lucretius Carus.
