Abstract

The issues discussed in this chapter concern peculiarities of the ancient Greek conception of a flat earth. As we will see in Part Two of this book, in the ancient Chinese gai tian system, everything, except the meaning of “falling,” is different. In the present chapter, there is necessarily some overlap with my earlier publications, but this is inevitable to show the differences between the two systems.

The suggestion in Panchenko (1999), that Archelaus, Leucippus and Democritus meant that the earth is shaped like a shield, concave at its lower side and convex at its upper side, is ingenious but not very convincing.

  11. 11.

    Aristotle mentions the argument in De Caelo 294a1–4. 4. I discussed it at length in Couprie (2008) and in Couprie (2011), Chap. 15.

  14. 14.

    Cf. Heidel (1937), 12 n. 22: “It is quite certain that the continental mass, not to speak of the οἰκουμένη, was not circular, though the map probably was in the earlier tines.”

  15. 15.

    Heidel (1937), 12. See also Berger (1903), 81 and Pédech (1976), 35. Some scholars divide the surface of the earth on the ancient maps in three parts. For instance, Robinson (1968), 32, and Naddaf (2003), 54, Fig. 1.1. This is, I think, a misunderstanding of another text, in which Herodotus says that the Ionians discerned three parts of the earth: Europe, Asia, and Libya, the river Nile being the border between Asia and Libya. Here, however, Herodotus is not talking about the oldest maps, but about later developments of maps, on which more details of lands were depicted.

    See next note.

  19. 19.

    Cf. MR 410–411: “In the standard Platonic-Aristotelian cosmological model both the cosmos and the earth cannot be said to be tilted.” Nevertheless, in order to visualize the inclination of the ecliptic, modern earth globes are usually positioned with a tilt of 23.5°. Mansfeld and Runia also rightly remark: “It needs some imagination to understand the problem raised in this chapter” (MR 410).

  20. 20.

    Cf. Kahn (1970), 102: “the term for this general tilting is always ἔγκλισις, whereas λοξὸς (κύκλος) is the technical expression for the obliquity of the ecliptic.” See also Dicks (1970), 71.

  22. 22.

    Cf. Heidel (1933), 122: “the early scientists contended that originally the sun had moved round the edge of the earth-plane.”

KRS does not print this text, but on p. 446 it is stated, completely confusing, “that the earth, which is a circle, presumably a round disc, is tilted toward the south (Aëtius II.8.1, DK 59A67) is ascribed also to Anaxagoras and Leucippus.” According to DK 59A67 not the earth but the cosmos is tilted. The tilt of the earth is nowhere ascribed to Anaxagoras, but to Leucippus and Democritus (see the next section on the alleged tilt of the earth).

As regards Democritus, we must probably distinguish three kinds of motion: the movements of the atoms, which is a random jostling because of collisions, the motion of the heavenly bodies, probably caused by the cosmic whirl, and the motion of heavy things, including the earth, which is downwards unless some other body prevents it. Cf. Furley (1989), 11–12.

    The first is P’s version (2.31.1), the second that of S (1.26.5), see Dox 362. Both versions in DK 31A61, followed by a kind of reconstruction of the original; LM EMP. D 136 and Gr Emp86 give P’s version, but that of S, in footnotes, without translation; MR give also both versions: 635 (S1.26.5 S1) and 636 (P2.31.1), but in their reconstruction, they follow P; neither version in KRS. According to Mansfeld (2000), 185, the genitive τῆς σελήνης in Stobaeus’ text is an obvious mistake.

    The angular size of the sun was not so easy to measure in those times; two centuries later, Aristarchus calculated with an angular diameter of 2°. With Aristarchus’ number, the size of the sun would have been about 275 km.
