In the context of this artwork, explain the Third Cod of the History.
The third Cod was installed in 1784 (the Committee continued) after Representative John Rowe‍—‌namesake of Rowes Wharf and "a leading spirit in the stirring scenes that led up to the famous 'Boston Tea Party'" [C]: 16 ‍—‌asked leave "to hang up the representation of a Cod Fish in the room where the House sit, as a memorial of the importance of the Cod-Fishery to the welfare of this Commonwealth, as had been usual formerly ... And so the emblem was suspended" in the old State House once again, and this Cod (which Rowe may have underwritten personally) is the one extant today.[C]: 20 In 1798 the Cod was moved to the Representatives chamber in the new State House,[C]: 12-13 
where it originally hung over the Speaker's desk. In the 1850s it was moved to the rear of the chamber.
