Sharing with you the beauty and "vagueness" of the mosaics in Santa Prassede church / St.Zenon Chapel in Rome, one of the very few examples of Byzantine mosaics in Rome. The name prassede derives from Greek meaning the one that acts, from the Greek word πράξις (praxis), action...think of the English word practice...I think it comes from the Greek praxis..? (I have a predilection for etymology...)
If you are ever in Rome go visit this church and the St.Zenon chapel to see the mosaics.
Looking at these mosaics, it is inevitable to think of Thessaloniki (Salonica in Greece) and the Rotunda mosaics and Ravenna though I see that these mosaics are inclined to resemble the mosaics in Ravenna in terms of the colour-focused approach rather than the linear-detailed fashion of the Rotunda mosaics on which I still have to dedicate a post!
