Ionic order that the Doric column had its initial basis in the proportions of the male body, while Ionic columns took on a "slenderness" inspired by the female body. Though he does not name his source for such a self-conscious and "literary" approach, it must be in traditions passed on from Hellenistic architects, such as Hermogenes of Priene, the architect of a famed temple of Artemis at Magnesia on the Meander in Lydia (now Turkey). Renaissance architectural theorists took his hints, to interpret the Ionic order as matronly in comparison to the Doric order, though not as wholly feminine as the Corinthian
Ionic radius to it. Ionic radius Ionic radius, "r", is the radius of an atom's ion in ionic crystals structure. Although neither atoms nor ions have sharp boundaries, they are sometimes treated as if they were hard spheres with radii such that the sum of ionic radii of the cation and anion gives the distance between the ions in a crystal lattice. Ionic radii are typically given in units of either picometers (pm) or angstroms (Å), with 1 Å = 100 pm. Typical values range from 30 pm (0.3 Å) to over 200 pm (2 Å). The concept can be extended to
