WILLIAMSTOWN, Mass. – He was as adept at drawing a charging brigade of Civil War soldiers as he was painting outdoorsmen scouting a mountaintop view in the Adirondacks.

And the seascapes illustrated from his vantage point on the rocky Maine coast captured an uneasy balance between the violence of white-capped ocean waves and the tranquility of a sunrise over the Atlantic’s horizon.

Winslow Homer was a chronicler of American times and a recorder of the country’s landscapes, a mostly self-taught artist who did not have to wait for a posthumous nod from critics and collectors who called him one of the most important artists of the 19th century.

A sweeping exhibit of Homer’s works on display through mid-January at the Clark Art Institute showcases the artist’s diversity of subjects and the mediums he chose to illustrate them.

“Winslow Homer: Making Art, Making History,” displays about 170 works from the Clark’s extensive collection of Homer’s engravings, etchings, watercolors and oil paintings.

“In all these realms, he achieved not only the highest levels of quality, but he altered what it meant to work in these mediums,” said Marc Simpson, the Clark’s curator of American art.

The wood engravings he did as a freelancer for magazines like Harper’s Weekly cast the mass-produced images as works of fine art. The works marked the start of the Boston native’s career as an artist and display his talent of being able to create realistic scenes from his imagination.

Although he was often commissioned to illustrate Civil War battle scenes, he never witnessed a confrontation between Union and Confederate soldiers. Not all his journalistic work focused on the war.

Several prints from his wood engraving drawings show the pleasant and bucolic side of America, with men and women gathered at social engagements and lumberjacks working on a winter day.

Homer started painting with oils when the war ended, and his works in the late 1860s and 1870s reflect a shift in the country’s focus from the ravages of war to the escapism of leisure activities.

He found plenty of inspiration in the mountains of the Northeast, where he painted a woman on horseback at the top of New Hampshire’s Mount Washington and a pair of woodsmen stopping along an Adirondack trail.

Homer’s compositions draw the viewer in, to see things from his subject’s perspective.

In “Two Guides,” Homer’s outdoorsmen stand at the center of the canvas. A glint of light reflects from the older man’s ax blade, first attracting the viewer’s eye and then leading it to follow the guide’s outstretched hand and the gaze of his younger companion.

But the painting leaves one nagging question: What are they looking at?

In 1873, Homer began working with watercolors, a medium that gave his work a looser feel. In “An October Day,” he frames a deer swimming across a mountain lake with the glowing colors of fall’s foliage reflecting off the water.

“He’s letting serendipity work its way throughout the image,” Simpson said.

He also tried his hand at etchings, doing some of the work he was most proud of. But after devoting most of his time to the medium after two years, he stopped doing etchings because they weren’t selling.

By the mid-1880s, Homer had moved to Prout’s Neck on the coast of Maine and produced some of the nautical images he’s most commonly associated with.

In “West Point, Prout’s Neck,” Homer’s sea splashes in the foreground as the sun casts a blaze of orange over the horizon.

While the Clark’s exhibit spans the shifts in Homer’s work, it also captures the museum founder’s fascination with the artist. Robert Sterling Clark began collecting Homer’s illustrations in 1916, six years after the artist died. Clark acquired more than 200 of Homer’s works between then and his last purchase in 1955.

“His collection of Homer is the best collection assembled by anyone since the artist’s death,” Simpson said.

While the exhibit doesn’t display all the museum’s holdings, it gives viewers an overwhelming sense of the scope of Homer’s work.

Pamela Allen, an art conservationist visiting the museum from Yorkshire, England, said she was surprised by the etchings and drawings she never associated with Homer.

“Much of what I’m seeing here is completely different from what I had expected from a Homer exhibit,” she said.
