, or beak-head
A piece of brass like a beak, fixed at the head of the ancient galleys, with which they pierced their enemies. Pisæus is said to have first added the rostrum or beak-head. Later it was a small platform at the fore part of the upper deck, but the term is now applied to that part without the ship before the forecastle, or knee of the head, which is fastened to the stem and is supported by the main knee. Latterly, to meet steam propulsion, the whole of this is enlarged, strengthened, and armed with iron plates, and thus the armed stem revives the ancient strategy in sea-fights. Shakspeare makes Ariel thus allude to the beak in the "Tempest:"
"I boarded the king's ship; now on the beak,
Now in the waist, the deck, in every cabin,
I flam'd amazement."
