Landschaft mit hochstämmigen Bäumen

The German title 'Landschaft mit hochstämmigen Bäumen' (Landscape with tall-stemmed trees) now in the Bavarian State Painting Collections describes Pynacker's signature compositional device of the tall, slender tree placed at the edge of the picture to act as a vertical repoussoir, a device he developed more consistently than any other Dutch Italianate painter. These tall trees — often an exotic species unknown in the Netherlands, perhaps a Mediterranean stone pine or a simplified version of a cypress — leaned slightly over the composition's interior, framing the scene and providing a scale reference against the distant landscape. The 1651 canvas marks Pynacker's early mature period, when this compositional device was still being developed rather than deployed by routine. The tree-framing motif became so associated with his work that it served as an informal signature: scholars identifying unsigned or disputed Italianate landscapes sometimes cite the distinctive tall-tree framing as evidence for Pynacker's authorship.

Oil on canvas, the tall trees are painted with a combination of structural brushwork for the trunk and branches and loose, leafy masses for the foliage. The trunk's smooth bark is rendered with vertical strokes of ochre, grey, and shadow, while the foliage is built up with short, curved marks in multiple greens applied over a yellow-green underlayer.
