Thank you

There were a lot of this. They also have a lot of pictorial tile work on buildings.

Glad you liked them.

But here there was as much going on under foot.

just to put the tiles down. Let alone the design work and cutting.

How old are these designs?

Here is the wiki page on Portuguese pavement. I thought they were tiles but they are stones. Were common in Brazil also.

Like so much art, it is a dying craft. Photography such as yours is the only way to preserve it for history. Thank you.
