ABACUS. Besides the former Account of the Abacus, I find that Mauclerc, in the Ionick Order, designs what the Workmen call and O.G. with a Fillet over it for the Abacus: Which Fillet is half the Breadth of the O.G. and he calls it the Fillet of the Abacus'.

Scamozzi calls a certain Hollow of Casement, which is the Capital of the Pedestal of the Tuscan Order, by his Name Abacus.
