A tondo is a Renaissance term for a circular work of art, either a painting or a sculpture. The word derives from the Italian rotondo, "round". The term is usually not used in English for small round paintings, but only those over about 60 cm in diameter, thus excluding many round portrait miniatures – for sculpture the threshold is rather lower.

Pottery of ancient Greece
Pottery, due to its relative durability, comprises a large part of the archaeological record of ancient Greece, and since there is so much of it, it has exerted a disproportionately large influence on our understanding of Greek society. The shards of pots discarded or buried in the 1st millennium BC are still the best guide available to understand the customary life and mind of the ancient Greeks. There were several vessels produced locally for everyday and kitchen use, yet finer pottery from regions such as Attica was imported by other civilizations throughout the Mediterranean, such as the Etruscans in Italy. There were a multitude of specific regional varieties, such as the South Italian ancient Greek pottery.
