CASCA. You shall confess that you are both deceived. Here, as I point my sword, the sun arises, Which is a great way growing on the south, Weighing the youthful season of the year. Some two months hence up higher toward the north He first presents his fire, and the high east Stands, as the Capitol, directly here.
BRUTUS. Give me your hands all over, one by one.
