42 Continued: the seasons
I.8.42.5 · Wachsmuth pp. 106-107
Spring is a season of the year blended from winter ending and summer beginning; or the season after winter and before summer. Summer is the season most thoroughly heated by the sun. Autumn is the blended season after summer and before winter. Winter is the season most thoroughly chilled, or the chilled air around the earth. Each year has two equinoxes and two solstices: equinoxes occur when night and day are equal, one in spring and the other in autumn; the solstices occur in summer and winter.287
42b ⟨Aëtius, Opinions⟩
I.8.42b · Wachsmuth pp. 107
Empedocles and the Stoics say that winter occurs when air predominates, being forced upward through condensation; summer occurs when fire predominates, as it is forced downward.288
42c ⟨Aëtius, Opinions⟩: planetary years
I.8.42c.1 · Wachsmuth pp. 107
A year of Saturn is a circuit of thirty years; of Jupiter, twelve; of Mars, two; of the sun, twelve months. Mercury and Venus have the same period, for they travel at an equal rate. The moon’s period is thirty days, for this is the complete month from appearance to conjunction.289
42c ⟨Aëtius⟩, continued: the great year
I.8.42c.2 · Wachsmuth pp. 107-108
The so-called great year occurs when the heavenly bodies return to the ⟨same⟩ positions from which they began their motion. Some place the great year in an eight-year cycle, others in a nineteen-year cycle, others in four times that number of years, and others in sixty ⟨less one⟩, including Oenopides and Pythagoras. Others place it in the so-called “head of Saturn”: this is the return of the seven planets, on that day, in their motion from the north.290 Heraclitus makes it eighteen thousand solar years. Diogenes the Stoic makes it three hundred and sixty-five years, each as long as the year according to Heraclitus.291
43 Scythinus, On Nature
I.8.43 · Wachsmuth pp. 108
Time is the last and first of all things, contains all things within itself, and is always one. Time that has passed does not depart from what is, along a road opposite to itself [pareōniatōn: unresolved]. For tomorrow will in fact be yesterday, and yesterday ⟨was⟩ tomorrow.292
44 Plutarch, Lives of Numa and Lycurgus
I.8.44 · Wachsmuth pp. 108
Many say that Numa added the months January and February, and that originally the Romans used only ten months for the year, just as some non-Greek peoples use three, and among the Greeks the Arcadians use four and the Acarnanians six. The Egyptians, they say, had a year of one month and then of four months. This is why the inhabitants of that country seem to be the most ancient and bring down an extraordinary number of years in their genealogies: they count months as years.293
45 Plato, Timaeus, ⟨with Aëtius⟩
I.8.45.1 · Wachsmuth pp. 109
Plato calls time a moving image of eternity, or the interval of the universe’s motion. It is generated in conception; its nature is the motion of heaven. For he says in the Timaeus as follows:294
45 Plato, Timaeus, continued
I.8.45.2 · Wachsmuth pp. 109
When the father who begot it saw it moving and alive, a created image of the everlasting gods, he admired it. Delighted, he conceived the plan of making it still more like its model. As the model itself is an everlasting living being, so he attempted, as far as possible, to make this whole universe such a being too. Now the nature of that living being was eternal, and it was impossible to attach this character in its entirety to what had come to be. He therefore conceived the plan of making a moving image of eternity. As he put things in order, he made, together with heaven, an enduring image of eternity: eternity remains in unity, while its image advances according to number. This image is what we have named time.295
45 Plato, Timaeus, continued
I.8.45.3 · Wachsmuth pp. 109-110
Days and nights, months and years did not exist before heaven came to be. At the time of its formation he contrived that they should come to be along with it. All these are parts of time, and “was” and “will be” are forms of time that have come to be. We mistakenly and unawares transfer them to everlasting ⟨being⟩. For we say that it was, is, and will be, whereas in a true account only “is” belongs to it. “Was” and “will be” should be said of becoming as it proceeds in time, for it is motion. What always remains unchangingly the same should neither grow older nor younger through time, nor have come to be at some time, nor have now come to be, nor be going to exist hereafter. None at all of the conditions that becoming attaches to things moving within perception belongs to it. Rather, these have arisen as forms of time, which imitates eternity and revolves according to number.296
45 Plato, Timaeus, continued
I.8.45.4 · Wachsmuth pp. 110
There are also statements such as these: what has become is what has become; what is becoming is what is becoming; what will become is what will become; and what is not is what is not. None of these expressions is exact. But perhaps this is not the right occasion to discuss them with precision. Time, then, came to be together with heaven, so that, having come to be together, they might also be dissolved together, should they ever undergo dissolution. It was made after the model of eternal nature, to be as like that model as possible. For the model is in being throughout all eternity, while heaven, continually throughout all time, has come to be, is, and will be.297
45 Plato, Timaeus, continued
I.8.45.5 · Wachsmuth pp. 110-111
From this reasoning and intention of the god concerning the creation of time, the sun, moon, and five other stars called wanderers came into being so that time might come to be, and so that its numbers could be distinguished and preserved. After making a body for each, the god set these seven bodies in the seven circuits traversed by the revolution of the Different: the moon in the first around the earth, the sun in the second above the earth, and the morning star and the star called sacred to Hermes in the circle that runs at the same speed as the sun, though they were allotted a power contrary to its own. Thus the sun, Hermes’ star, and the morning star alike overtake and are overtaken by one another.298 As for where he placed the others and all the reasons for doing so, an account of every detail, though incidental, would make more work than the subject for whose sake it is given.
45 Plato, Timaeus, continued
I.8.45.6 · Wachsmuth pp. 111
…
Nevertheless, it is still possible to understand that the complete number of time fulfills the complete year when the relative speeds of all eight revolutions, having completed their courses together, reach their culmination, measured by the circle of the Same, which moves uniformly.299
