Questions of attribution have captured the minds of art connoisseurs for centuries. Many works of art have been attributed and reattributed repeatedly over the course of their existence. One of the most vexing issues is whether a work is by a master, student, or even a copy by a later follower. Several paintings in the Clowes Collection at the Indianapolis Museum of Art pose just this question, but technical art history and scientific investigation have helped us further our understanding of how, and by whom, these paintings were made. Two examples that will be discussed is the reattribution of a portrait, most recently thought to be a 19<sup>th</sup> century copy of a Rembrandt, to the workshop of Rembrandt himself and the ongoing research into a series of small portraits, attributed to the circle of the enigmatic artist Corneille de Lyon, which have perplexed scholars for generations.
