Part of a European tour, the paintings traveling through London, Tallinn, Copenhagen and Glasgow are being studied by an international team of art experts for clues about their obvious similiarities, but also striking differences. One of the pieces is owned by the Kadriorg Art Museum.

The 16th-century Dutch compositions are close replicas on the subject "Christ Driving Money-lenders from the Temple."

The exhibits will demonstrate methods used by art conservationists, including infrared and X-ray scanners, to peek into the layers of the paintings.

"The sheer number of these four high quality replicas, as well as the composition itself, gives us reason to ascribe the invention of the composition to one of the most innovative and influential artists of the 16th century, [Bosch], or to the young Pieter Bruegel the Elder (1527-1569), who in the 16th century was nicknamed 'the second Bosch'," the project's organizers say on their website, which was launched on April 29, and includes an events schedule.
