 1   I,  2|       the bodies that move in a circle, and besides this four bodies
 2   I,  6|      extent of the whole of its circle before it reappears at the
 3   I,  6|      because the segment of its circle which is above the horizon
 4   I,  6|       the planets appear in the circle of the zodiac, whereas many
 5   I,  6|     have been seen outside that circle. Again more comets than
 6   I,  7|      days about the equinoctial circle (this one had not risen
 7   I,  8|       used once to move in this circle and that this region was
 8   I,  8|        this were the reason the circle of the Zodiac ought to be
 9   I,  8|       can see the whole of this circle (half of it being visible
10   I,  8|        a part of it touches the circle of the milky way.~(2) Anaxagoras,
11   I,  8|        it is clearly a greatest circle), whereas, since the sun
12   I,  8|  constellations included in the circle of the milky way move; and
13   I,  8|         to one another. Now the circle of the zodiac dissolves
14   I,  8|         its formation. But this circle in which the milky way appears
15   I,  8|       our sight is the greatest circle, and its position is such
16   I,  8|      the theory is this: In the circle itself the light is stronger
17   I,  8|       For if it is found in the circle in which there are most
18   I,  8|        and at that point in the circle at which they are densest
19   I,  8|      affection in question. The circle and the constellations in
20   I,  8|     point is clear. For in this circle alone are the intervals
21   I,  8|      way in relation to a whole circle. So if we are to define
22   I,  8|       attaching to the greatest circle, and due to the matter secreted".
23   I,  9|    chief and first cause is the circle in which the sun moves.
24   I,  9|        flowing up and down in a circle and made up partly of air,
25   I,  9|      this river that flows in a circle about the earth.~So the
26  II,  2|      them come round again in a circle to the original source of
27  II,  5|      the other the ever visible circle, their vertex is at the
28  II,  6|          sake we have drawn the circle of the horizon, which is
29  II,  6| coincides with the ever visible circle, but not quite.) These winds
30 III,  1|         and so the wind forms a circle and eddy. It is prevented
31 III,  1|    becomes one, that is, till a circle is formed: for if a figure
32 III,  1|       density, first moves in a circle for the reason given and
33 III,  2|     often appears as a complete circle: it is seen round the sun
34 III,  2|      rainbow never forms a full circle, nor any segment greater
35 III,  2|       At sunset and sunrise the circle is smallest and the segment
36 III,  2|        the sun rises higher the circle is larger and the segment
37 III,  3|        of the halo; why it is a circle and why it appears round
38 III,  3|         result is necessarily a circle or a segment of a circle:
39 III,  3|        circle or a segment of a circle: for if the lines start
40 III,  3|      angle will always lie on a circle.~Let AGB and AZB and ADB
41 III,  3|      draw the line it will be a circle and E its centre. Now B
42 III,  3|         sun, which is seen as a circle, appearing successively
43 III,  4|        of the lamp appears as a circle which is not white but purple.
44 III,  5|      The rainbow can never be a circle nor a segment of a circle
45 III,  5|       circle nor a segment of a circle greater than a semicircle.
46 III,  5|       hemisphere resting on the circle of the horizon, let its
47 III,  5|       on the circumference of a circle. If the reflection takes
48 III,  5|      setting the segment of the circle above the earth which is
49 III,  5|      the sphere will be a great circle. Let it be A (for it makes
50 III,  5|       Then I is the pole of the circle on which the lines from
51 III,  5|   finally MH to MK.~If, then, a circle be described with I as pole
52 III,  5|     Then O is the centre of the circle, half of which, MN, is cut
53 III,  5|   before, but the pole I of the circle will be below the horizon
54 III,  5|     pole, and the centre of the circle, and the centre of that
55 III,  5|          and the centre of that circle (namely HI) which now determines
56 III,  5|       KI below the plane of the circle AG determined the position
57 III,  5|      pole and the centre of the circle will be.~In the shorter
