The monk Bede (c. 672–735) wrote in his influential treatise on computus, The Reckoning of Time, that Earth was round. He explained the unequal length of daylight from
"the roundness of the Earth, for not without reason is it called 'the orb of the world' on the pages of Holy Scripture and of ordinary literature. It is, in fact, set like a sphere in the middle of the whole universe." (De temporum ratione, 32)
The latin word that Bede uses is "pila". It can mean ball, sphere. It can ALSO mean mortar, pier, pillar, pile.
The point is, this is not very descriptive. But if we look for other parts where St Bede describes roundness, he envisions that the heavens (i.e. atmosphere) make up part of this sphere, not simply the land mass. See below, he uses the word "gyrum":
Ch 16: He says "the gyre of the heavens, perfectly round at every point, is bound by the line of the zodiacal circle...adjacent to each other on a sort of girdle wrapped around a very large sphere."
Seems to me, he's including the heavens in the overall globe sphere, and the zodiac circle wraps around the heavens.
