Massachusetts' seal features several elements:
The motto, "Ense petit placidam sub libertate quietem" ("By the sword we seek peace, but peace only under liberty") was written by Algernon Sidney, presumably sometime before he was executed for treason.a shield having a blue field or surface with an Indian thereon, dressed in a shirt and moccasins, holding in his right hand a bow, and in his left hand an arrow, point downward, all of gold; and, in the upper corner of the field, above his right arm, a silver star with five points. The crest is a wreath of blue and gold, on which in gold is a right arm, bent at the elbow, clothed and ruffled, with the hand grasping a broadsword.
My favorite part of the seal has always been the disembodied arm swinging the sword. There's a Massachusetts monument at Gettysburg that has an arm rising out of the top — when I was a child, it always made me think of zombies.
According to the Secretary of the Commonwealth, the sword was first added to the seal in 1775, but it doesn't seem to have become disembodied until at least 1780. Yet, we find it on the Benjamin Chamberlin gravestone in Pepperell, MA (dated 1778):
There are a few possibilities here:
- the arm and sword motif may have been circulating in Massachusetts before Nathan Cushing designed the seal in 1780
- the Benjamin Chamberlin stone may have been carved after 1780

*I say this, of course, with the caveat that I know nothing about heraldry. It may fit the conventions very nicely, but I still think it's ugly.
**The best state seals (in no particular order): Rhode Island, Texas, Louisiana. Mississippi would be a contender if they hadn't just lifted their design from the US seal.
