These charming engraved glass scenes were likely drawn from known prints or engravings at the time of their creation. Wheel-engraved glass and crystal techniques in northern Europe developed first in Bohemia around 1600 and flourished in the Netherlands in the second half of the 17^th century (see Pieter C. Ritsema van Eck, “Early Wheel Engraving in the Netherlands,” Journal of Glass Studies, vol. 26, 1984, pp. 86-101). Glass panes of even thickness could be skillfully cut and polished and given a reflective backing with the use of a very fine tin foil applied with mercury (see Loek van Aalst and Annigje Hofstede, Noord-Nederlandse meubelen van renaissance tot vroege barok 1550-1670, Amsterdam, 2011, pp. 58-59). Similarly crafted small panels such as these can be found in the Rijksmuseum, such as a regal mirrored glass portrait of Princess Caroline by Christiaan Schröder from 1757 (BK-1966-63-B), and at the Kunstmuseum den Haag, with a portrait of Prince William IV, also by Christiaan Schröder around 1757 (1004662).
