Ignatius Press: Confessiosn of a Traditional Catholic by Matthew Arnold

The book features an oil lamp (or candle holder) that is typically used in Byzantine temples or homes, especially hanging in front of an icon, but not in Latin temples. Roman Catholics, even traditionalists, prefer their bleached candles, which generally go with their statues. Rarely will they put candles in front of a religious paintings. Though perhaps I may have seen this in Rome, but was the candle for the painting or the altar? So why was this particular image used for book? It was probably the decision of the publisher and not the author. To add a greater sense of ritual or piety or mystique that would be missing with a candle?
