"We shall ... assume that the earth is spheroidal, that its surface is likewise spheroidal, and above all, that bodies have a tendency [to fall] towards its centre, which latter point is obvious to everybody. However we may show briefly that the earth is spheroidal, from the consideration that all things however distant are attracted to its centre, and that every body is attracted towards its centre of gravity; this is more distinctly proved from observations of the sea and sky, for here the evidence of the senses, and common observation, is enough to prove the point. The convexity of the sea is a further proof of this to those who have sailed; for they cannot perceive lights at a distance when placed at the same level as their eyes, but if raised on high, they at once become perceptible to vision, though at the same time further removed. So, when the eye is raised, it sees what before was utterly imperceptible. Homer speaks of this when he says, Lifted up on the vast wave he quickly beheld afar.

Sailors, as they approach their destination, behold the shore continually raising itself to their view; and objects which had at first seemed low, begin to elevate themselves. Our sundials, also, are, among other things, evidence of the revolution of the heavenly bodies; and common sense at once shows us, that if the depth of the earth were infinite, such a revolution could not take place." -

Strabo, Geography, first C. BC, trans. M. C. Hamilton, 1856 [Project Gutenburg] Strabo makes several arguments above for the Earth being spherical, not flat. Take any one of these arguments and explain what he means by it. Be sure to state Strabo's argument in your own words but back it up with a direct quotation (even if only a word or two) from the passage. Direct quotations must be in quotation marks "like this".
