This is the spring window. The legend of the dogwood is that Christ's crucifix was made of the wood from a dogwood tree and since that time, the dogwood has never grown large enough to be used for that purpose again. The dogwood flower expresses the new life and hope of spring as well as the Resurrection.
Spring is the end of the penitential season and the beginning of the renewal of life.
Red, the color of the cardinals, denotes hope, life, immortality and fruitfulness. This is the summer window. The fish, mountains and water represent summer. Water also represents baptism. Fish were the earliest Christian symbol.
