Ovolo

Decoration inside: six linked palmettes with 9 petals around a band of ovolos between incised lines, surrounded by 13 palmettes linked around a band of ovolos.

Each of the pairs is connected by a kind of web, and each pair stands clear of the ovolo and astragal mouldings which form a kind of extension to the column shaft and complete the essential construction of the capital. Ovolo and astragal are enriched with egg and dart and bead and reel respectively, the setting out related to a fluting pattern of twenty-four flutes to the column shaft circumference, as shown on the plan.

Using a template or a good eye to guide the paring chisel, slice off the corners of the tenon ovolos at 45 degrees.
