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 radii. The relation between soft-sphere ionic radii, formula_2 and formula_3, and formula_1, is given by formula_5, where formula_6 is an exponent that varies with the type of crystal structure. In the hard-sphere model, formula_6 would be 1, giving formula_8. In the soft-sphere model, formula_6 has a value between 1 and 2. For example, for crystals of group 1 halides with the sodium chloride structure, a value of 1.6667 gives good agreement with experiment. Some soft-sphere ionic radii are in the table. These radii are larger than the crystal radii given above (Li, 90 pm; Cl, 167 pm). Inter-ionic separations calculated
