Can anyone bring me proofs from the Gemara that proves the world was round-and that this was known 2000+ years ago?

I have looked around and I can't seem to find any sources which prove this.

Do you mean circular or spherical? –  Double AA Jun 11 '14 at 13:53
    
I dont mean to offensively psychoanalyze you, but why do you ask? If you are assuming that Chazal knew all science and seek support, be aware that even the relatively "right-wing" (no pejorative intent) book 'Torah, Chazal, & Science' makes no such assertion. [Rather his general thesis is that Chazal's definitive statements are true just as they are in halacha. That is , if they were sure enough of themselves to make a statement, we assume they are right. However, regarding something they didnt comment on, we dont need to assume that they were fully aware.] –  mevaqesh Feb 17 at 2:47

See Gemara and Tosfos Avoda Zara (41a K'Kadur)enter image description here

shetofes es atzmo tachas kol haolam kulo k'kadurenter image description here

"shetofes es atzmo tachas kol haolam kulo k'kadur"

Tosfos says "Because the World is round"

Tosfos references a Yerushalmi which echoes this point: "Alexander the Macedonian ascended on high until he saw the earth like a ball and the sea like a platter. The 'sea' refers to the ocean that encompasses the entire earth"

Also see the Yaavet'z on this Tosfos in the back of the gemara

This is a good answer (and +1), but it would be greatly improved if it featured a translation into English. Especially of the passage in the Yerushalmi, since that's the part that best answers the question that was asked. –  Shimon bM Jun 10 '14 at 11:13
    
I haven't looked it up, but just from what you copied here of the tosafos I don't see it as difficult? "The world is spherical, as it says in the Yerushalmi: Alexander the Macedonian ascended on high until he saw the earth like a ball and the sea like a platter. The 'sea' refers to the ocean that encompasses the entire earth". –  Shimon bM Jun 10 '14 at 11:25
    
@Nafkamina Looks like an accurate translation to me. –  Cnsersmoit Jun 10 '14 at 11:34
    
Could someone translate this for me please? –  user5523 Jun 10 '14 at 12:54
