A BIG Armorial Memorial in Granary Burying Ground, Boston

One of the largest memorials, with heraldry or not, in Granary Burying Ground in Boston, Massachusetts, is that memorializing John Hancock.

I trust that I don’t really have to give you the biography of John Hancock, the Massachusetts merchant (and smuggler) whose signature appears so large on the Declaration of Independence. If you want to know more about him, he has his own (very long) entry in Wikipedia, at https://en.wikipedia.org/wiki/John_Hancock

That article also has a color image of his coat of arms.

The monolith here is clearly not contemporaneous with Mr. Hancock’s death, being plainly 20th century in style. But above the bust of Mr. Hancock, at its top it has the carved Hancock coat of arms, complete with crest and motto.

Bolton’s An American Armory cites: Hancock. Gules a dexter hand couped erect on a chief argent three cocks gules.
        Crest: A cock gules holding a dexter hand couped at the wrist argent.

And Crozier’s General Armory cites: Hancock. Massachusetts. Nathaniel Hancock, Cambridge, 1652. Gules a hand couped and erect on a chief argent three cocks gules.
        Crest: A cock gules holding a dexter hand couped at the wrist argent.

The crest on the monument differs from those cited, being A demi-griffin wings elevated and addorsed. Oddly, the demi-griffin issues from a torse of seven twists, rather than the usual six.

The motto underneath the arms reads Obsta principiis, "Contrary to principles". I'm not sure what that is supposed to mean. I am tempted to read it as a misspelling of Obsta principis (with a single instead of a double "i"), which translates as "Contrary to the prince", which certainly fits well with Mr. Hancock's participation in the Americn Revolution as being "contrary to the Prince" in the person of King George III.
