"This was the most unkindest cut of all; For when the noble Cæsar saw him stab, Ingratitude, more strong than traitor's arms, Quite vanquish'd him; then burst his mighty heart; And, in his mantle muffling, up his face, Even at the base of Pompey's statue, Which all the while ran blood, great Cæsar fell."
