When I was being taught about the history of art and architecture I learnt to to distinguish anthemion and palmette ornament on the basis that the former was derived from the honeysuckle flower and the latter from palm leaves. Today, it seems, that distinction no longer applies and the two types of Egyptian, classical and renaissance ornament are grouped as variations of a single form. That is an unusual trend: usually finer classifications prevail over a reduction in types. The anthemion design in today's photograph is part of the cast iron railings that formed part of the perimeter of Gloucester Docks and is presumably of the late Georgian or, more likely, Victorian period.
