GALLERIES

The high point of the week is the new exhibit that opened Monday at the Busch-Reisinger Museum. A collection of sixty-nine photographs of illustrations from a medieval Swiss Chronicle, the show illustrates life and society in Switzerland (particularly Lucerne and Basel) in the 14th and 15th centuries. The reproductions are excellent (the original is locked up in Lucerne), the drawings are imaginative and the world depicted is very odd. A murder trial consisted of holding the accused's right hand over the corpse of the victim. If the hand bled, the man was guilty and was drawn and quartered. All shown in living color. Through Nov. 8.

Museum of Fine Arts. Through Dec. 8, prints by Pablo Picasso. Etchings and Lithographs, all part of a collection he made in the '80s for critic Ambroise Vollard.

At Graphics 1 and Graphics 2, 168 Newbury St. in Boston, lithographs from Ellsworth Kelly's plant series. Kelly, a major abstract artist, made these representational prints of Cyclamens, Magnolias, Camelias and lemon branches in 1964. Through Nov. 16, the Gallery is open Mon.-Sat. 9:30-5:30.
