At Eternity's Gate is a lithograph that was completed by Vincent van Gogh in 1882.
Later, Van Gogh did a painting based on the lithograph, that is referred to as, Old Man in Sorrow (On the Threshold of Eternity).
Vincent did the painting on his own lithograph from 1882.
The lithograph was titled, At Eternity's Gate, then when Van Gogh did the painting in 1890, he titled it, Old Man in Sorrow (On the Threshold of Eternity).
The painting shows us a very old man sitting in a chair by a fire.
His head is resting in his hands.
It seems to show us that the man is lonely, depressed and tired.
Van Gogh did the painting while he was hospitalized in Saint-Remy.
