Opus Africanum or building with stone uprights

Is a Latin term used to describe a method of building with stone uprights. Essentially,walls were constructed out of rubble stone but strengthened at regular intervals with large carefully made squared slabs and stones uprights, referred to in technical language as orthostats.In general these orthostats are as thick as the wall in which they are placed.There are no rules however for their other dimension, varying from one wall to an other. In any given wall, orthostats of different heights and outside facing widths can be observed.
