This painting depicts a figure in profile, seated at a table against a sage green wall. They wear a high-necked black dress with a white pinafore or apron, and their dark hair is gathered in a neat bun. Through a window to their left, dried cattails or reeds stand against a bright yellow field and blue sky with wispy clouds. On the yellow-topped table before the figure sit three tall black candlesticks. The composition creates a sense of quiet contemplation, with the figure's gaze directed toward the distant view, suggesting the "endless" nature referenced in the title. The limited color palette of blacks, whites, yellows and sage green gives the piece a stark, clean feeling that emphasizes its geometric elements and sense of stillness.
