• swerve off sure: if "Eve and Adam's" can refer to "even atoms" in the Epicurean sense, the word "swerve" can refer to what the Roman poet Titus Lucretius Carus calls the clinamen, or the "swerve" ever so slightly from 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). See Lucretius, De Rerum Natura ("On the Nature of Things"), Book II, lines 216-224: "And this, too, understand: when bodies thus / Are borne sheer down through void by their own weight, / At times and points of space unfixed, they swerve / A little from their line, just so much as / That you can mark the change. If 'twere not so / They all would fall just like the drops of rain / Straight through the void: there would have been no clash, / No blow inflicted on the seeds, and so / Had nature ne'er begotten autht at all." For clinamen, see the Latin text: Book II, line 292.
