His seas are seldom calm -- they boil and they roar. Sunsets rip his skies. The North Atlantic seascapes of the aging Winslow Homer must be among the grandest ever made by an American. "Winslow Homer in the 1890s: Prout's Neck Observed," the touring show now visiting the National Museum of American Art, brings us 15 of his oils. It's not a large exhibit. It nonetheless feels mighty. When you step into the gallery, the beauty of the paintings -- their drama and ferocity -- almost knocks you down.

THEATER The good theater news this week is that Jon Spelman's low-key and mesmerizing one-man show at the Woolly Mammoth on Monday and Tuesday mights has been extended through March 26. The performance artist as storyteller, Spelman's experiences with fatherhood and the loss of his parents, as well as things like nearly sinking into a volcano, have given him his unique take on mortality. Alternately funny and poetic, at times nearly mystical, Spelman is the best company imaginable, not to be missed.

At Arena Stage, Douglas C. Wager has directed a "Pygmalion" that comes out from under the romantic shadow of "My Fair Lady" and returns to Shaw's thorny, tough-minded world. As the pedantic Henry Higgins and his acerbic mother, Richard Bauer and Tammy Grimes are perfectly believable as son and mother -- they seem to come from the same eccentric planet; the comedy planet, perhaps. Bauer's Higgins is frequently hilarious, but he's also moving: an idealist who ends up the victim of his own ideals. This is Shaw done not only with humor but with real intelligence -- it becomes about the cost our principles exact from us. Wager reminds us that though the play is less emotionally satisfying than the musical, it's far greater.
