Albrecht Durer's three Meisterstiche "master prints"

Melencolia I is a large 1514 engraving by the German Renaissance artist Albrecht Dürer. Its central subject is an enigmatic and gloomy winged female figure thought to be a personification of melancholia – melancholy. Holding her head in her hand, she stares past the busy scene in front of her. The area is strewn with symbols and tools associated with craft and carpentry, including an hourglass, weighing scales, a hand plane, a claw hammer, and a saw. Other objects relate to alchemy, geometry or numerology. Behind the figure is a structure with an embedded magic square, and a ladder leading beyond the frame. The sky contains a rainbow, a comet or planet, and a bat-like creature bearing the text that has become the print's title.

Knight, Death and the Devil is a large 1513 engraving by the German artist Albrecht Dürer. A stolid armoured knight on a proud horse, accompanied by his faithful dog, rides through a wild narrow gorge flanked by a goat-headed devil and the figure of death riding a pale horse. Death's rotting corpse holds an hourglass, a reminder of the shortness of life. The rider moves through the scene looking away from the creatures lurking around him, and appears almost contemptuous of the threats, and is thus often seen as symbol of courage; the knight's armour, the horse which towers in size over the beasts, and the oak leaves are symbolic of the resilience of faith, while the knight's plight may represent Christians' earthly journey towards the Kingdom of Heaven symbolized by the city on the hill.

Saint Jerome in His Study is a copper engraving of 1514 by the German artist Albrecht Dürer. Saint Jerome is shown sitting behind his desk, engrossed in work. The table, on the corner of which is a cross, is typical of the Renaissance. An imaginary line from Jerome's head passing through the cross would arrive at the skull on the window ledge, as if contrasting death and the Resurrection. The lion in the foreground is part of the traditional iconography of St. Jerome, and near it is a sleeping dog, an animal found frequently in Dürer's works, symbolizing loyalty. 

Jerome is also often depicted with a lion, in reference to the popular hagiographical belief that Jerome had tamed a lion in the wilderness by healing its paw. 

The positioning of the Crucifix on Jerome's desk is such that when he looks at it he can also see the skull by the window. Looking at the crucifix reminds of the resurrection of Jesus, which righted the wrongs of Adam leading to death, represented by the skull. The hourglass represents the finite space of time that is a man's life. Viewing these symbols together leads to the thought of man's mortality, and the method by which to save the immortal soul.
