Here is a description which I thought was particularly effective among those you submitted. Note which comments and points relate to your strengths and to the points that I suggested that you will want to improve in your subsequent writing . The mosaic decoration of the dome of the Baptistery at Ravenna is a piece which immediately caught my eye. The dome is covered totally in an intricate mosaic with three distinct tiers to it.
All sections are lavishly detailed.
There is also a sense of swirling movement, due to the tier with the apostles. The lowest, and largest in diameter, is a series of faux architectural pieces. The other four centers hold altars. The flanking niches of each group are filled with what look to be chairs and fences around little gardens. The objects in the niches are all set in place so that they appear to recede into space, as do the imaginary compartments themselves.
