One of the fun things about studying ornament is finding common threads and unusual variations on a theme. One that I noticed in Pompeii last summer was this Corinthian column in the Basilica, which bears an uncanny resemblance to the columns in the Temple of Vesta at Tivoli, and is the only other place that I have seen this type of capital (other than modern variations). It's the ruffled and curled over vertical edges of the acanthus leaves that makes them distinctive; most other acanthus leaves have more prominent tops, while the sides are relatively flat. Here's a few images to illustrate what I'm talking about.
|Corinthian capital in the Basilica at Pompeii. Notice the curly edges of the acanthus leaves.|

|Capital at the Temple of Vesta at Tivoli also has the ruffled edges of the acanthus leaves. It also has flutes that end without being rounded|
|A more typical Roman style corinthian capital, as seen at the Pantheon. Here the tops of the acanthus leaves are the most pronounced part of the bell.|
|The Ionic style capitals also have an interesting variant with "Quail egg" and dart, a style I have not seen elsewhere. This is also in the Basilica.|
