How rough is that!
Roman mosaics, how neat should we try to be?
As with tilers working now there are varying standards of work in the Roman mosaics that we have. Some were obviously done by craftsmen at the top of their game, others were more 'basic' in their execution! Overall though if you get up really close to one, so you can easily see each individual tesserae, then you will notice that very few are that neat.
