idea-idea awal mengenai tokoh bumi memegang bumi, dan langit dome fizikal yang merangkuminya. dua hujah awal untuk bumi sfera adalah bahawa gerhana bulan dilihat sebagai bayang-bayang bulatan yang hanya boleh disebabkan oleh bumi sfera, dan bahawa polaris dilihat lebih rendah di langit sebagai salah satu perjalanan selatan. orang yunani awal, dalam spekulasi dan teori mereka, berkisar dari cakera rata yang disokong oleh homer kepada badan sfera yang disebarkan oleh pythagoras - idea yang disokong kemudian
