In this painting of Boston Harbor in the 1860s, a ship carrying a passenger sits in the center, while an assortment of seafaring vessels dots the hazy horizon. In the foreground, birds fly low among waves that reflect the colors of the sky. Manger’s use of glowing light and smooth brushstrokes was a popular approach among American landscape painters at the time. This work was completed around the time of the American Civil War when Boston Harbor served as a training camp and coastal defense for the Union army.
