About this work
You’re looking at soft green hills, a winding stream, and a few bare trees under a pale sky.
You’re looking at soft green hills, a winding stream, and a few bare trees under a pale sky. The colors are light, almost like a watercolor sketch.
Sonntag painted this in 1890, when most artists were working in oil. Using gouache—opaque watercolor—lets him layer colors without losing brightness. The paper’s rough texture shows through, giving the scene a quiet, unfinished feel.

Overview
Created in 1890, this work by William Louis Sonntag presents a tranquil rural scene rendered in gouache and watercolor on off‑white wove paper. The composition centers on gentle, verdant hills that slope toward a meandering stream, punctuated by sparse, leaf‑less trees beneath a muted sky. The overall effect is one of quiet observation, emphasizing the subtle tonal variations of the landscape.
Subject & Meaning
The painting captures a modest stretch of countryside, focusing on the relationship between land and water. The soft hills and winding stream suggest a passage through nature, while the bare trees evoke a sense of seasonal transition. The restrained palette and simplified forms invite contemplation of the landscape’s inherent calm rather than dramatizing any particular narrative.
Technique & Style
Sonntag employed gouache, an opaque watercolor, allowing him to build layered washes while preserving luminosity. The medium’s capacity for both transparency and solidity gives the hills a gentle depth without the heaviness of oil. The paper’s slightly textured surface remains visible, contributing to an unfinished, sketch‑like quality that underscores the work’s immediacy and atmospheric subtlety.
History & Provenance
Executed at a time when many American artists favored oil painting, this piece reflects Sonntag’s preference for watercolor media in the late nineteenth century. It entered the American Wing collection of the museum through acquisition in the early twentieth century, where it has been displayed as part of the institution’s representation of American landscape traditions.
