The acanthus () is one of the most common plant forms to make foliage ornament and decoration in the architectural tradition emanating from Greece and Rome.
The relationship between acanthus ornament and the acanthus plant has been the subject of a long-standing controversy. Alois Riegl argued in his Stilfragen that acanthus ornament originated as a sculptural version of the palmette, and only later began to resemble Acanthus spinosus.
The Roman writer Vitruvius (c. 75 – c. 15 BC) related that the Corinthian order had been invented by Callimachus, a Greek architect and sculptor who was inspired by the sight of a votive basket that had been left on the grave of a young girl. A few of her toys were in it, and a square tile had been placed over the basket, to protect them from the weather. An acanthus plant had grown through the woven basket, mixing its spiny, deeply cut leaves with the weave of the basket.
