Anathyrosis

Anathyrosis (fem., also Anathyrose, from Greek θύρα - the door ) is the term for a certain technical processing of bearing surfaces on ancient stone architecture in the Greek and Roman construction. At Werksteinbauten where the stone blocks were directly added without mortar and without any other compensation materials and each other, the bearing and shock surfaces had to be worked exactly as possible. To limit the effort required for this purpose, connecting surfaces only in a narrow border strips were (referred to as the hem Anathyrose ) along the visible surfaces or the outer edges of the block finely smoothed and adjusted. The inner portion of the lands referred to as mirror, however, was executed more depth with the coarser tool to avoid that has been achieved due to the above points, a dense joint lock.

This technique was used in ashlar mainly to abutting surfaces, while for reasons of stability on the bearing surfaces indoors usually not in-depth, but often somewhat coarser worked out - with the chisels and not with the iron tooth. For these very similar processing Anathyrose the term is generally not used. Chance is also on storage areas the processing observed with Anathyrose, especially when using dense, so to end up consuming processed and sustainable stone material so frequently on marble column drums or pier shaft pieces.

Close observation of this technical details can give about where a member was sitting inside a building or whether further stones were with him in the dressing shed.
