This article is about a flower structure. For the mathematician, see Pappus of Alexandria.
Pappus, in a composite flower, is the element of the individual disk and ray flowers that surrounds the flower structure, in the same manner at the base as calyx does in a non-compound flower. Pappuses may be like bristles, teeth or scales and are usually too diminutive to discern without some type of magnification device. The etymology of this name is that it derives from the Ancient Greek word pappos, Latinpappus, meaning old man, but also used for a plant – assumed to be an Erigeron species – having bristles, and also for the woolly, hairy seed of certain plants.

She argues persuasively that Pappus attempts in this book to present himself as the key representative or authority in a discipline, mathematics, which he regards as superior to philosophy because it proves what philosophers take for granted, paradigmatically, that the sphere is the largest of all regular polyhedra with the same surface area.
Pappus defines mechanics as the science of the rest and motion (both natural and contrary to nature) of bodies in the universe, and distinguishes the theoretical part which embraces the mathematical and natural sciences from the practical part which involves craft.
As Cuomo shows, Pappus' account of mechanics serves to incorporate previous views of what mechanics is in such a way that their differences are at once recognized and mitigated, thus allowing him to present himself as a leading proponent of a science with a tradition that goes back to Archimedes and includes Ptolemy.
