This painting by Botticelli shows Saint Augustine talking with a child on the beach, who was trying to scoop the sea water into a hole. According to the Web Gallery of Art, the child tells the bishop that it's easier to spoon the sea into the hole than it is to explain the mystery of the Trinity. After speaking the child disappeared.
Saint Augustine, a bishop and doctor of the early Christian Church, was an important figure in the history of Christianity. Saint Augustine wrote about topics like predestination and original sin. Some of his doctrines separate Western and Eastern Christianity.
Saint Augustine was born on 13 November 354, at Tagaste, in North Africa, and died in 28 August 430, at Hippo, where the Vandals were attacking the city.
