Antique painting of hilly landscape, oil on canvas from the late 19th century

In this evocative composition, a majestic, ancient oak tree draws the viewer's attention to the foreground. The artist's exceptional skill is evident in the meticulous detail, vibrant application of colour and masterful use of light, which beautifully highlights the outlines of the trees in the foreground as they gradually blend into the shadowy depths of the forest beyond. The initials 'ST' are present in the lower left corner but the artist has not been identified and the painting is not authenticated. The painting is elegantly presented in an antique wooden frame which has some defects. Price negotiable.
