Old Pine Trees is one of Hertervig’s main works from his second large oil painting period. The motif is a fantasy landscape based on sketches of virgin forests near Tysvær. The three focal trees represent the forest’s rotting process, and stand in contrast to a clear, restful sky. The composition is punctuated by a verticality that disrupts the rationalized composition we find in Hertervig’s earlier paintings, of foreground, mid-ground and background. Contrasting sizes of pictorial elements are intensified when one notices, on the picture’s left side, tiny figures standing by a tree on a crag.
