“In the figurative arts, one does not create or compose well except when concepts are perfectly assigned to form. Similarly, in writing, one does not invent or compose well without mastering words, phrases, grammar and syntax.”

*“ Original Language: Nelle arti figurative non si inventa o compone bene se non quando ai concetti si sa appropriare abilmente la forma, come nello scrivere non s’inventa o compone bene senza essere padroni delle parole, delle frasi, della grammatica, della sintassi.“ (Boito, 1897)

“The wall consists of natural stone, maybe limestone (it’s not clear from the picture). The stones seem to be of same size and left roughly hewn, called rockfaced work. In some of the rows, the surface of the stones appears to be more bulky. The joints have been remodeled, which could be an indication that the look of anisodome ashlar work was achieved afterwards, to hides light differences in the size of the stones.” (Lisa)

“This example of stonework is presumably not pure sandstone but a harder stone, such as a limestone or a mixture of a sand- and limestone, which can be determined by the rather large grain size. In the beginning of the design process the architect or engineer draws a plan of this stonework. At the quarry boulders are split by using hand tools. In rock-faced work the edges are pitched off to a line, while the face of the stone is left rough. The surface is finished in broached-work, which is washed out trough humidity or salt influence on the stones at the bottom of the picture. Block-in-course / blocked-course ashlar is laid with stone of the same height but different lengths, and it is not attempted to have the joints come over one another.” (Sabrina)

“The opus reticulatum is a masonry type widely used in Roman times from the beginning of the first century BC until the imperial period (1st century AC). It takes its name from the net-like appearance of the joints, inclined on a 45 degree angle towards the ground. The stones, also called cubilia, are cut out of volcanic tuff stone in a pyramidal shape, with the square base placed towards the outside and the tapered part on the inside. This enables a full adhesion of the two enclosing stone facings to the Roman concrete (opus caementicium) of the wall core”. (Ana)
