minute work in ivory, and especially for a chariot which a fly covered with its wings, and a ship
which the wings of a bee concealed. See Plin. Nat. Hist. VII. 21, XXXVI. 5.
§121. Posse: n. on I. 29. Strato: R. and P. 331. Sed cum: sed often marks a very slight contrast,
there is no need to read et, as Halm. Asperis ... corporibus: cf. fragm. 28 of the Ac. Post., also
N.D. I. 66. Somnia: so N.D. I. 18 miracula non disserentium philosophorum sed somniantium, ib.
I. 42 non philosophorum iudicia sed delirantium somnia, also ib. I. 66 flagitia Democriti.
Docentis: giving proof. Optantis: Guietus humorously conj. potantis, Durand oscitantis (cf. N.D.
I. 72), others opinantis. That the text is sound however may be seen from T.D. II. 30 optare hoc
quidem est non docere, De Fato 46, N.D. I. 19 optata magis quam inventa, ib. III. 12 doceas
oportet nec proferas; cf. also Orat. 59 vocis bonitas optanda est, non est enim in nobis, i.e. a
good voice is a thing to be prayed for, and not to be got by exertion. There is a similar Greek
proverb, e??? µa???? ? a???e?a, in Sext. P.H. VIII. 353. Magno opere: Hermann wishes to read
onere. The phrase magnum onus is indeed common (cf. De Or. I. 116), but magnum opus, in the
sense of "a great task," is equally so, cf. T.D. III. 79, 84, Orat. 75. Modo hoc modo illud: 134.
§122. Latent ista: see n. on fragm. 29 of the Ac. Post.; for latent cf. I. 45. Aug. Cont. Ac. II. 12,
III. 1 imitates this passage. Circumfusa: cf. I. 44, and 46 of this book. Medici: cf. T.D. I. 46
Viderentur: a genuine passive, cf. 25, 39, 81. Empirici: a school of physicians so called. Ut ...
mutentur: exactly the same answer was made recently to Prof. Huxley's speculations on
protoplasm; he was said to have assumed that the living protoplasm would have the same
properties as the dead. Media pendeat: cf. N.D. II. 98, De Or. III. 178.
§123. Habitari ait: for this edd. qu. Lactant. Inst. III. 23, 12. Portenta: "monstrosities these," cf.
D.F. IV. 70. Iurare: cf. 116. Neque ego, etc.: see fragm. 30 of Ac. Post. ??t?p?da?: this doctrine
appears in Philolaus (see Plut. Plac. Phil. III. 11 qu. R. and P. 75), who give the name of a?t????
? to the opposite side of the world. Diog. VIII. 26 (with which passage cf. Stob. Phys. XV. 7)
mentions the theory as Pythagorean, but in another passage (III. 24) says that Plato first invented
the name. The word a?t?p??? seems to occur first in Plat. Tim. 63 A. The existence of a?t?p?
de?; was of course bound up with the doctrine that the universe or the world is a globe (which is
held by Plat. in the Tim. and by the Stoics, see Stob. Phys. XV. 6, Diog. VII. 140), hence the early
Christian writers attack the two ideas together as unscriptural. Cf. esp Aug. De Civ. Dei XVI. 9.
Hicetas: he was followed by Heraclides Ponticus and some Pythagoreans. Sext. A.M. X. 174
speaks of the followers of Aristarchus the mathematician as holding the same doctrine. It seems
also to be found in Philolaus, see R. and P. 75. Theophrastus: who wrote much on the history of
philosophy, see R. and P. 328. Platonem: the words of Plato (Tim. 40 B) are ??? de t??f?? µe? ?
?µete?a?, e????µe??? de pe?? t?? d?a pa?t?? p???? tetaµe???. Quid tu, Epicure: the
connection is that Cic., having given the crotchets of other philosophers about f?s???, proceeds
to give the peculiar crotchet of Epic. Putas solem ... tantum: a hard passage. Egone? ne bis is the
em. of Lamb. for MSS. egone vobis, and is approved by Madv., who thus explains it (Em. 185)
"cum interrogatum esset num tantulum (quasi pedalem 82) solem esse putaret, Epic. non
praecise definit (tantum enim esse censebat quantus videretur vel paulo aut maiorem aut
minorem) sed latius circumscribit, ne bis quidem tantum esse, sed inter pedalem magnitudinem
et bipedalem". (D.F. I. 20) This explanation though not quite satisfactory is the best yet given.
Epicurus' absurdity is by Cic. brought into strong relief by stating the outside limit to which Epic.
was prepared to go in estimating the sun's size, i.e. twice the apparent size. Ne ... quidem may
possibly appear strange, cf. however ne maiorem quidem in 82. Aristo Chius: for this doctrine of
his see R. and P. 358.
§124. Quid sit animus: an enumeration of the different ancient theories is given in T.D. I. 18—22,
and by Sext. A.M. VII. 113, who also speaks in P.H. II. 31 of the p???? ?a? a????t?? µa??
concerning the soul. In P.H. II. 57 he says G????a? ??de d?a???a? e??a? f?s?. Dicaearcho:
T.D. I. 21. Tres partis: in Plato's Republic. Ignis: Zeno's opinion, T.D. I. 19. Animam: ib. I. 19.
Sanguis: Empodocles, as in T.D. I. 19 where his famous line ?a?µa ?a? a????p??? pe???a?d???
est? ???µa is translated, see R. and P. 124. Ut Xenocrates: some edd. read Xenocrati, but cf. I.
