“Outside Influences Through the Seasons” is the title of Allen’s solo exhibition at Shelburne’s Furchgott Sourdiffe Gallery, and its meaning is straightforward: Like many a landscape painter, the Vermont artist finds inspiration in the quotidian beauty of nature and its inexorable fluctuations over a year. With classic, unpeopled compositions and a lightly impressionistic brush, Allen appears to extol the transcendent, enraptured with color, light and atmosphere. “Being at one with nature brings a sense of serenity,” she writes, “but also sharpens one’s skills of observations.”
