The Minoan civilization produced a wide variety of richly decorated Minoan pottery. Its restless sequence of quirky maturing artistic styles reveals something of Minoan patrons' pleasure in novelty while they assist archaeologists in assigning relative dates to the strata of their sites. Pots that contained oils and ointments, exported from 18th century BC Crete, have been found at sites through the Aegean islands and mainland Greece, in Cyprus, along coastal Syria and in Egypt, showing the wide trading contacts of the Minoans.
