I've gotten through the God of War's door, but I can't reach his temple.

Hint 1 of 19:

The jaws that are to the left and right of the entrance are the key to
opening the first door that you will encounter.  (Note that left and right
mean the directions that were left and right when you first got through the
doorway to this area.)

Hint 2 of 19:

When you open the one on the left, the door will open, and opening the one on
the right will stop the spears that are flying across the doorway.

Hint 3 of 19:

You'll need to get both of the jaws to stay open to get through the door.

Hint 4 of 19:

Put something in them that might be found as the result of war (and death).
