In the context of this artwork, explain the World War II of the "Cod-napping" and other incidents.
After the House of Representatives moved to its new chamber in 1895, the Massachusetts Senate, which took over the old House chamber, incorporated a fish figure
(often dubbed the Holy Mackerel)
into the chandelier there, as a reminder of the Sacred Cod the Representatives had taken with them.
When officials of the World War II aluminum-for-defense drive‍—‌misinformed that the Sacred Cod was aluminum‍—‌asked that it be donated to the war effort, House Speaker Christian Herter explained that the Cod had been created decades before aluminum's discovery, and suggested that the Holy Mackerel be considered for sacrifice instead.
