The column bases of about 460 Greek monuments from (proto)geometric to late Hellenistic times in the Greek home territory and on the Peloponnese, the Greek islands and in Asia minor, as well as examples from Greek colonies of the Magna Graecia and others, are covered. Twelve different types of Greek column, some variants and modifications and a few special forms can be distinguished. The different types were studied for their distribution, choice of materials, combination with forms of columns and building styles, form, fluting or decoration, proprotions, dating, origin, derivation, stone carving and technique; the results are summarised in a synopsis spanning all the different forms. The “foot” of the Ionian or Corinthian column, in contrast to the shaft and the capital, provided room for creative design; the individually formed types of column bases with a particular area of distribution were used as a characteristic form of expression for local architectural traditions.
