The gardens of king Herod seem to have been an important part of the architectural layout of his winter palace at Jericho in Israel. Various rows of pots, thought to be flower pots, were found in situ within the gardens. The only other site where these pots have been found is Pompeii at the foot of Mount Vesuvius in Italy. Instrumental neutron activation analysis (INAA) showed that the pots were a local product of the Jericho potter who was either the first to make these vessels, or who imitated them from the western Roman Empire.
