Ito man nanirahan sa oras ng unang Ptolemy; para sa Archimedes, na malapit na kapag sinundan ang unang Ptolemy gumagawa ng anuman ng mga Euclid, at ang karagdagang sila sinasabi na ang Ptolemy minsan nagtanong siya kung may shorted ay isang paraan sa pag-aaral geometry kaysa sa Sangkap, na kung saan siya ay tumugon na wala ang hari ng daan sa geometry.
