Pausing on their nocturnal walk through a mountain forest is a couple on a rise beside a dramatically contorted, uprooted oak. Darkness envelops the strollers; their eyes are raised to the reassuring celestial light of the moon that permeates the atmosphere with a solemn stillness. Deep in the moonlit night the trees and rocks acquire strange, almost eerie, dimensions and importance. The two figures are united by their shared experience of the natural world confronting them with an awareness of their transience; together they face the mystery of the unfathomable. The date of origin of this painting is disputed; various dates between 1818 and 1835 have been proposed.
