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 compound by a specific equilibrium distance. If the electronic structure of the two interacting bodies is affected by the presence of one another, covalent interactions (non-ionic) also contribute to the overall energy of the compound formed. Ionic compounds are rarely purely ionic, i.e. held together only by electrostatic forces. The bonds between even the most electronegative/electropositive pairs such as those in caesium fluoride exhibit a small degree of covalency. Conversely, covalent bonds between unlike atoms often exhibit some charge separation and can be considered to have a partial ionic character. The circumstances under which a compound will have ionic or covalent
