Meaning

Koilos is hollow or concave. A description of apparent shape need not assert the object’s actual internal structure.

Use in the book

Aratus treats a hollow-looking solar disk as an unfavorable weather sign. The phrase concerns how the sun appears under atmospheric conditions, in contrast with a clear and unmarked disk. It should not be converted into a claim that the sun is physically an empty shell.

Places to read

  1. I.25.9.1A hollow-seeming disk is interpreted as a sign of rain or wind.

Translation in this edition

“Hollow-seeming” keeps the passage’s explicit distinction between appearance and composition.
