The work depicts the four stages of human life through allegorical figures, each accompanied by symbolic objects. Childhood is represented by a boy with a saddened look that holds an empty bird trap, symbolizing innocence and naivety, as the bird escaped. Youth is a young man who plays a lute, representing his lust for life, while adulthood is a man in armor, with his eyes closed and resting his head in one hand. He is wearing a victor’s laurel wreath and holding an open book. All these symbols represent strength, achievement, and learning. Old age is represented by an elderly figure, sitting beside coins, symbolizing greed, and holding a glass, as a reminder of the efemerity of life. All the characters, except adulthood, are looking in the viewers direction.[3][4]
The composition reflects Baroque painting interest in moral allegory, emphasizing the transience of human existence and the inevitability of decline.[5]
