Corinthian order girl, as thick and much taller than a Doric one, which is designed to represent the bulk and vigour of a muscular full grown man. The oldest known example of a Corinthian column is in the Temple of Apollo Epicurius at Bassae in Arcadia, c. 450–420 BC. It is not part of the order of the temple itself, which has a Doric colonnade surrounding the temple and an Ionic order within the cella enclosure. A single Corinthian column stands free, centered within the cella. This is a mysterious feature, and archaeologists debate what this shows: some state that it is
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
