diameter geometrical concept

Τοῦ δὲ κόσμου σφαιροειδοῦς ὑπάρχοντος ἄξων καλεῖται ἡ διάμετρος τοῦ κόσμου, περὶ ἣν στρέφεται ὁ κόσμος. Τὰ δὲ πέρατα τοῦ ἄξονος πόλοι λέγονται τοῦ κόσμου.

‘Since the cosmos is spherical, the diameter of the cosmos around which the cosmos turns, is called “axis”. The extremities of the axis are called “poles of the cosmos”.’
