The attribution to Wagner is based on a comparison of the present box with a gold-mounted box made for Frederick the Great, signed and dated 1741. The interior of its cover is stippled with a similar scene depicting Minerva as Prussia enthroned and receiving homage from the Arts. The figure of Arithmetic holds a scroll inscribed with numbers whose sum equal the date 1741. On the present box, the scroll held by Poetry is inscribed with the alphabet from a - k. The faces of the Muses have similar features.

Cf. Christie's Geneva, May 8, 1989, lot 109; also Barbara Beauchamp-Markowsky, Porzellandosen des 18. Jahrhunderts, Munich, 1985, no. 103 for a Meissen box also painted with scenes reserved within gilt cartouches on a blue-mosaic ground
