Undertow

Winslow Homer's 'Undertow' (1886) is one of his most physically dramatic marine paintings, depicting the actual danger of the undertow — the invisible current beneath breaking waves that pulls bathers away from shore. The painting shows two female bathers being rescued by two male lifeguards, their bodies entwined in the physical struggle between the rescuers' effort and the sea's pull. Homer had witnessed beach rescues at Prout's Neck, Maine, and Atlantic City, and brought to this subject the same commitment to depicting actual physical danger — unsentimentalized and specific — that characterized his Civil War paintings.

Homer organizes the composition around the physical struggle between the four figures and the sea — the waves breaking around them as the rescuers drag the bathers toward shore. His handling of the ocean is powerful and specific, the undertow's invisible force conveyed through the exhausted bathers' weighted forms. His marine technique had reached full maturity by 1886, the sea rendered with authoritative knowledge of its physical behavior.
