In architecture, what does the term 'caryatid' refer to?

The term 'caryatid' specifically refers to a female figure that is sculpted in a way that serves as a support for an architectural structure, effectively replacing a traditional column. This design element not only provides structural support but also adds artistic and aesthetic value to buildings, particularly in classical architecture. The use of caryatids can be seen prominently in structures such as the Erechtheion on the Acropolis in Athens, where the figures are intricately designed to enhance both the visual appeal and the functionality of the architecture. This melding of form and function exemplifies the creativity and skill involved in architectural sculpture.
