Artist and retired professor Susan Wadsworth will present a four-part spring lecture series, โ€œWhy is this art?โ€ at the Jaffrey Civic Center, examining the development of modern abstraction.

Programs begin at 1:30 p.m. on Wednesdays at the center, 40 Main St., Jaffrey. Topics include โ€œPicasso and Braque and Cubism: Why is this art?โ€ on March 18; โ€œGeorgia Oโ€™Keeffe and Early American Modernism: Why is this art?โ€ on April 22; โ€œJackson Pollock and Mark Rothko: Why is this art?โ€ on May 20; and โ€œEarthworks and Light: Why are these works art?โ€ on June 17.

The informal presentations will explore shifts in artistic styles from the late nineteenth through the twentieth centuries and invite audience questions.

Wadsworth, of Rindge, holds a Master of Fine Arts from Cranbrook Academy of Art and an MA in art history from Tufts. She taught art history and studio art at Fitchburg State for 27 years.

The series is free; donations are welcome.
