The little birds under the angles of the abaci should not be overlooked.
From these were derived the abaci of the Chinese and Russians.
The abaci of the capitals are either square or octagonal in plan.
In Romanesque and Gothic work the capitals with their abaci take the place of the impost mouldings.
The capitals here are very close imitations of Classical work, with the abaci frequently concave on plan.
The columns stand less than their diameter apart, and the abaci are so broad that they nearly touch.
But the abaci of its capitals run from the jambs across to the buttresses, as is the case with those of the doorway.
These abaci, which are finely moulded, are not more than about two and a half inches in depth.
The abaci are new, and the angle-shafts and bases as well, but the capitals are old, though decayed.
The abaci are all square in plan, and both bases and caps are set at right angles to the direction of the arches they support.
