Which aspects of Paul Gauguin’s style influenced Edvard Munch?

Edvard Munch’s artistic development was significantly shaped by his exposure to the work of Paul Gauguin starting around 1890.1

The primary aspects of Gauguin’s style that influenced Munch include:

• The Bounding Line: While Munch experimented with the open brushstrokes of the Impressionists, he found Gauguin’s use of the "bounding line" to be more compatible with his own artistic goals.12
• Synthetism: Munch was highly receptive to Gauguin’s Synthetism, a style that moved beyond the mere depiction of external nature to give form to an "inner vision".1

By adopting these techniques, Munch moved away from the naturalist aesthetic that had previously dominated his work in Kristiania, allowing him to better express his own philosophical and emotional themes.1
