SUMMARY
Tadeusz Kosciuszko’s Oath - Michał Stachowicz's Painting from the Polish Hero’s Catafalque Decoration.
History and Conservation of the Work
In late 2016 and early 2017, the National Museum in Krakow hosted the conservation and restoration
treatment of Michal Stachowicz's painting Tadeusz Kościuszko's Oath, which was one of the four pieces
executed in 1818 as decoration of the catafalque for the Polish national hero's coffin. The treatment was
carried out to prepare the painting to be loaned to the Presidential Palace in Warsaw, where, alongside
three other paintings of the same provenance, it decorates the official staircase. The four works were pa-
inted en grisaille (grey tones heightened with whites) in tempera on canvas. The unique character of their
original purpose, a rather poorly durable technology (the manner of painting and materials employed)
62 as well as their later complicated history contributed to the fact that the paintings were in a poor state
of preservation when they were acquired by the museum. The major conservation problem turned out to
be extensive losses in the paint layer involving the primer as well as the detachment of these layers from
the canvas. The conservation treatment involved research into the history of Tadeusz Kościuszko's Oath,
its iconography as well as technique of execution that cast some light on the treated work. An analysis
of the extant sketches was performed and the iconography of the persons accompanying Kościuszko in
the historical event was researched and compiled. The presented text discusses the investigation results
complete with conservation-related problems.
