Corinthian order simply an example of a votive column. A few examples of Corinthian columns in Greece during the next century are all used "inside" temples. A more famous example, and the first documented use of the Corinthian order on the exterior of a structure, is the circular Choragic Monument of Lysicrates in Athens, erected c. 334 BC. A Corinthian capital carefully buried in antiquity in the foundations of the circular "tholos" at Epidaurus was recovered during modern archaeological campaigns. Its enigmatic presence and preservation have been explained as a sculptor's model for stonemasons to follow in erecting the temple dedicated to
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
