While in Iznájar, Andalusia, Spain, I walked across the Plaza de la Venta. Under the lanterns four till walls are present; my eye catches a snail on one of them beneath some poems. It is a stylised dextral specimen.
According to the marks on two of the tile walls, the design was made by Antonio Quintana. No date is given, but I suppose the tiles were made during the 20th century.
