Some philosophy-cum-science from Ronsard: Plato did not believe in the existence of a vacuum (or perhaps rather any ‘void’/emptiness) in the world, Ronsard answers that there must be or he’ll over-fill everything with his tears. (I’ve copied his double-negative in the opening quatrain: I must say working through the grammar here was rather testing!) Plato held that the universe was continually ‘becoming’ – self-generating – so that any temporary gaps between matter would be filled by this process; at the beginning of the sestet Ronsard is referring to these arguments about the nature of its ‘becoming’. As always, he turns the intellectual discussion to an extravagant love metaphor, in a charming fashion. Fortunately the earlier Blanchemain version is substantially similar, with only minor variants in the language. In line 4, the Styx “emmure” (‘walls in’ rather than ‘surrounds’) the underworld; in line 5 the air is filled “en sa courbure humide” (‘in its wet curvature’ instead of ‘in its watery vault’); and in line 9 “Il est du vague, ou certes, s’il n’en est” (‘It is from emptiness, or certainly if not’, rather than ‘if not from there’). The next sonnet, no.82, can be found here. [ PS. I am amused to see the opening phrase re-used, with a twist, half way through this sonnet in the Marie set! I’m sure that’s entirely deliberate.]
