Flower Mausoleum, Allegheny Cemetery

This mausoleum from the early 1920s is an interesting and unusual design: a little bit Egyptian in shape, but without Egyptian details. The gorgeous stained glass inside is full of nautical references, which must refer in some way to the William S. Flower who is recorded as the first burial here in 1924. Does anyone know their significance? A Dr. William S. Flower was a dentist here in the early twentieth century, but Father Pitt cannot guess what sailing ships, hourglasses, and classical dolphins have to do with dentistry.
