opus isodomum การใช้

It is the finest stone masonry unit, generally cuboid, mentioned by Vitruvius as opus isodomum, or less frequently trapezoidal.
Although slowly eroded, there are still segments of the wall, composed of Opus isodomum, that connected the semi-circular corbels / towers.
Vitruvius further states that the stone blocks of opus isodomum are bound together by mortar, but more often they are not connected with mortar but with metal ties such as iron cramps, fixed in stone blocks with molten lead.
"' Opus pseudoisodomum "'is a version of opus isodomum mentioned by Vitruvius, describing that it is a kind of stonemasonery in which " the rows of courses do not match but run unequally ", referring to the height and length of the blocks, which are nevertheless still perfectly cut.
