canephorae is applied to caryatids, figures of young persons of either sex supporting baskets on their heads.(in architecture).
I did a little self education to find the origin of "Vizcayads". Technically our Stone Barge statues are cross between a herm and a canephorae but Vizcanephorae doesn't sound as good. The most famous caryatids are probably on the Acropolis in Athens Greece. I included a picture from the Acropolis with our Vizcayads for comparison.
