In 1884, Janez Šubic left for Bavarian Kaiserslautern at the invitation of architect Karl Spatz, who designed the new building to house the Museum Pfalzgalerie and served as its first director. The palace was built in the style of Renaissance Revival and decorated exaggeratedly. Šubic accepted an offer to paint the ceiling in the great hall, the hallway, and 2 loggias with 7 domes and 7 arched niches and windows each. The commission was impressive in scope and required several years of work to complete, and so Šubic had several assistants on hand who completed tasks according to his plans.
Šubic had ambitious designs for the iconography, painting 2 huge paintings for the ceiling, namely allegorical depictions of Strength and Abundance, as well as 56 oval and 112 circular miniatures for the loggias with scenes from world history and the spiritual and political lives of various nations, while the other surfaces were fleshed out with depictions of other allegories and personifications, such as that of Peace (Pax) and Labor, whose sketches are housed at the National Gallery.
In 1885, Šubic also assumed the role of professor of ornamental painting at the arts and trade school operating under the museum’s auspices. A fire broke out at the museum in the same year, destroying all the paintings and forcing Šubic to start again from scratch.
The personification of Pax is replete with its characteristic attributes such as the laurel crown in her hair, the palm leaf in her right hand, and white doves upon her, while Labor is depicted in a Herculean pose, dressed in work clothes, and surrounded by tools.
