The symbolic meaning of the title "Painted Veil"

The Painted Veil is a novel by British author W. Somerset Maugham, which was written in 1925. It reflected the vices and the virtues of that time, but which remain relevant to this day. People make the same mistakes for centuries, but virtues haven`t changed too. In this work we can see the love, betrayal, kindness, contempt, nobility, hatred and honor- something that does not change over the centuries, the eternal concepts that accompany people at all times.
