Paintings by Monogrammist I.S. Sought for Exhibition

Serlachius Museums in Mänttä and Museum De Lakenhal in Leiden are looking for information about several paintings attributed to the Monogrammist I.S.

The two museums are collaborating on an exhibition about the work of this enigmatic artist, who was active between 1632 and 1658. Little is known about his or her identity, except that they seem to have worked in Leiden and traveled through Scandinavia and/or Eastern Europe. The exhibition is scheduled from 12 April until 17 Augustus 2025 in Mänttä and from 10 October 2025 until 8 March 2026 in Leiden.
