Orchidaceae is a diverse and widespread family of flowering plants, with blooms that are often colourful and often fragrant. The type genus (i.e. the genus after which the family is named) is Orchis. The genus name comes from the Ancient Greek ὄρχις (órkhis), literally meaning “testicle”, because of the shape of the twin tubers in some species of Orchis. The term “orchid” was introduced in 1845 by John Lindley in School Botany, as a shortened form of Orchidaceae. All orchids are perennial herbs that lack any permanent woody structure.
The depictions of Italian orchids showed up much earlier than expected. Previously they were spotted in paintings in the 1400s, but Caneva’s team discovered them as early as 46 B.C.E, when Julius Caesar erected the Temple of Venus Genetrix in Rome. There are at least three orchids appearing in dozens of other plants on the Ara Pacis. Artists chose the flowers to emphasize a theme of civic rebirth, fertility and prosperity following a long period of conflict.
As Christianity began to influence art in the 3rd and 4th centuries, orchids and other plants began to fade from public art. This was probably due to an effort to eliminate pagan symbols and those related to sexuality. With the arrival of the Renaissance, orchids arrive back in art, but now mostly as a symbol of beauty and elegance.
