Abstract

The article presents problems connected to the management of iconographic data using computer science tools. In particular, the authors discuss especially the computerised management of Athenian figure-decorated pottery which represents perhaps the most relevant set of iconographic patterns in classical antiquity. Up to now this pottery has been investigated by means of quantitative analyses to study in particular the mechanics of ancient trade in the Mediterranean basin because Athenian vases, from 6th to 4th century BC were widely exported all around this area. The computerisation of iconographic information, however, presents many difficulties: in fact archaeologists tend to express iconic information by means of linguistic sentences which are often inadequate; moreover there are still many problems about the correct interpretation of representations on attic pottery. On this subject, the authors illustrate a project on Athenian decorated pottery found at Spina, the Etruscan “emporion” of the Upper Adriatic, where the most impressive collection of Athenian decorated vases of the 5th century BC was discovered. A database has been created which collects data on 2132 clay decorated vases made in Athens: iconographic information is represented both with a description in natural language and by means of terms of a thesaurus conceived for this purpose. The database has also been explored through statistical analyses, such as Correspondence Analysis and Multidimensional Scaling, to find significative interrelationships between shapes and subjects, to identify associations between the different subjects represented on the same vase and to stress changes, as time passed, with regard to shapes and subjects.
