Sculpture 'Miraculous catch' was made in the form of a sundial where the shadow indicates the time of Jesus and speaks of eternity for the converts to the faith of Christ. According to the Gospel of Christ came from the East and that is why He is located in the eastern part of the composition. There are the zodiakal signs placed on the steps of the pool showing the constellations preceding the birth of the Savior and the world that He created.
And it came to pass, that, as the people pressed upon him to hear the word of God, he stood by the lake of Gennesaret, And saw ships standing by the lake: but the fishermen were gone out of them, and were washing their nets. And he entered into one of the ships, which was Simon's, and prayed him that he would thrust out a little from the land. And he sat down, and taught the people out of the ship. Now when he had left speaking, he said unto Simon, Launch out into the deep, and let down your nets for a draught. And Simon answering said unto him, Master, we have toiled all the night, and have taken nothing: nevertheless at thy word I will let down the net. And when they had this done, they inclosed a great multitude of fishes: and their net brake. And they beckoned unto their partners, which were in the other ship, that they should come and help them. And they came, and filled the ships, so that they began to sink. When Simon Peter saw it, he fell down at Jesus' knees, saying, Depart from me; for I am a sinful man, O Lord. For he was astonished, and all that were with him, at the draught of the fishes which they had taken: And so was also James, and John, the sons of Zebedee, which were partners with Simon. And Jesus said unto Simon, Fear not; from henceforth thou shalt catch men. And when they had brought their ships to land, they forsook all, and followed him.
