[The opening chapters are lost. There must have been an introduction of the speakers, with some explanation as to time and place, a reference to a set discussion at which some of the speakers had been present, and a promise of Sylla to narrate a myth, bearing upon the moon and her markings, which he had heard in Carthage. This conversation had taken a turn, prematurely as SYLLA thinks, towards the mythical or supernatural aspects of the moon.] But see note (1) on p. 309. c. 1. It is agreed that the current scientific or quasi-scientific views on the markings of the moon’s face shall be first considered, then the supernatural. cc. 2-4. LAMPRIAS mentions (i) The view that the markings are due to weakness of human eyesight. This is easily refuted. (ii) The view of Clearchus, the Peripatetic, that they are caused by reflexion of the ocean on the moon’s face. But ocean is continuous, the markings are broken; they are seen from all parts of the earth, including ocean itself (and the earth is not a mere point in space, but has dimensions of its own); and, thirdly, they are not seen on any other heavenly body. c. 3. The mention of Clearchus brings up the view, adopted from him by the Stoics, that the moon is not a solid or earth-like body, but is fire or air, like the stars. This view had been severely handled in the former conference. c. 6. PHARNACES complains that the Academics always criticize, never submit to be criticized. Let them first answer for their own paradox in confusing ‘up’ and ‘down’, if they place a heavy body, such as the moon is now said to be, above. LUCIUS retorts: ‘Why not the moon as well as the earth, a larger body, yet poised in space?’ PHARNACES is unconvinced. cc. 7-15. To give Lucius time to remember his points, LAMPRIAS reviews the absurd consequences from the Stoic tenet that all weights converge towards the centre of our earth. Why should not every heavy body, not earth only, attract its parts towards its own centre? Again, if the moon is a light fiery body, how do we find her placed near the earth and immeasurably far from the sun, planets, and stars? How can we assume that earth is the middle point of the Whole, that is, of Infinity? Lastly, allow that the Moon, if a heavy body, is out of her natural place. Yet why not? She may have been removed by force from the place naturally assigned to her to one which was better. Here the tone of the speaker rises as he lays down, often following the thought and the words of Plato’s _Timaeus_, the theory of creative ‘Necessity’ and ‘The Better’.
