Da farko daga gudunmawar Euclid da Archimedes kan darasin, ya kawo su jihar kafin ƙirƙirar analytic geometry. Bayanansa dangane da ma'anar kalmomi irinsu ellipse, parabola, da hyperbola sune waɗanda ake amfani da su a yau. Gottfried Wilhelm Leibniz ya ce "Wanda ya fahimci Archimedes da Apollonius ba zai gaza yabawa nasarorin da manyan mutanen zamanin baya suka samu ba."

There is the question of exactly what event occurred 246 - 222, whether birth or education. Scholars of the 19th and earlier 20th centuries tend to favor an earlier birth, 260 or 262, in an effort to make Apollonius more the age-mate of Archimedes. Some inscriptional evidence that turned up at Pompeii make Philonides the best dated character. He lived in the 2nd century BC. Since Apollonius' life must be extended into the 2nd century, early birth dates are less likely. A more detailed presentation of the data and problems may be found in

. The dichotomy between conventional dates deriving from tradition and a more realistic approach is shown by  McElroy at once gives 262 - 190 (high-side dates) and explains that it should be late 3rd - early 2nd as it is in this article.
