When Marcus Brutus he           complete,
And strove to hurl him out by blow on blow
Upon the marble, at Art's thunderheat,
Till haply (some pre-shadow rising slow
Of what his Italy would fancy meet
To be called BRUTUS) straight his plastic hand
Fell back before his prophet-soul, and left
A fragment, a maimed Brutus,--but more grand
Than this, so named at Rome, was!
