Squall off Cape Palos / Entrance to Cartagena

Miner Kilbourne Kellogg's paired maritime sketches depict seascapes in sharply contrasting conditions. The upper composition captures a violent squall with towering waves and dark, roiling clouds rendered in bold blue and black ink. Below, the same waters appear calm, with merchant vessels and sailing ships anchored near land under clement skies. Kellogg, a Hudson River School landscape painter and draftsman, combined his training in oil painting with rapid pen studies to capture atmospheric effects and nautical incident. These sketches demonstrate the 19th-century artist's practice of recording visual observations for future studio compositions, revealing both technical mastery and the documentary impulse that animated American landscape art.
