The Voyage of Life series, painted by Thomas Cole in 1840, is a series of paintings that represent an allegory of the four stages of human life: childhood, youth, manhood, and old age. The paintings follow a voyager who travels in a boat on a river through the mid-19th century American wilderness. In each painting, accompanied by a guardian angel, the voyager rides the boat on the River of Life.

Thomas Cole (February 1, 1801 – February 11, 1848) was an English-born American artist. He is regarded as the founder of the Hudson River School, an American art movement that flourished in the mid-19th century. Cole's Hudson River School, as well as his own work, was known for its realistic and detailed portrayal of American landscape and wilderness, which feature themes of romanticism and naturalism.
