The story of the word

Kônos was the pine cone first and the geometric solid second, and it also named the peak of a helmet that held the crest. Apollonius of Perga wrote eight books on conic sections around 200 BC, working out the ellipse, parabola and hyperbola long before anyone needed them for planetary orbits. Conifer is Latin for cone-bearing. The cone cells of the eye were named in the nineteenth century for their taper, and the ice cream cone showed up at fairgrounds around 1904.
