In Kate Greenaway's Language of Flowers, the entry for Acanthus reads: The fine arts. Artifice.
Read both parts of the entry
Acanthus receives a pairing that is more complicated than a simple compliment. Fine arts suggests creative achievement; artifice can introduce a less straightforward idea of constructed appearance. Leaving the second term out changes the historical entry.
An art-themed caption can mention the first association while acknowledging the wording as a whole. Do not turn this brief dictionary line into a claim about an artist's intentions or a universal meaning of acanthus ornament without separate evidence.
FAQ
Does an acanthus motif prove an artwork refers to this dictionary?
No. A shared plant motif does not establish that a particular artist used Greenaway's interpretation.
