Pease ad loc.: ‘Roman writers often use axis… in a figurative sense… for the caelum as a whole, and in our passage, while the force is applied by Atlas to the axis of the sphere, yet the whole sphere is apparently in mind, as the phrase stellis ardentibus aptum indicates.’ It is lexicographical commonplace that axis is used, especially in the poets, as a synonym for the sky, yet the oddity of the synecdoche by which a scientific, or pseudoscientific, term (...) for the axis of the universe is transferred to mean the heavens in general has been little commented on; unanalytic recognition of the semantic fact is the norm . I believe that a more precise account of this transference can be given, and in particular I will argue that Virgilian usage in the Aeneid is central to the history of this process. (shrink)
