(Mighty) Shelley said, in A Defence of Poetry:
…The life of Camillus, the death of Regulus; the expectation of the senators, in their godlike state, of the victorious Gauls; the refusal of the republic to make peace with Hannibal, after the battle of Cannae, were not the consequences of a refined calculation of the probable personal advantage to result from such a rhythm and order in the shows of life, to those who were at once the poets and the actors of these immortal dramas. The imagination beholding the beauty of this order, created it out of itself according to its own idea; the consequence was empire, and the reward everlasting fame. These things are not the less poetry, quia carent vate sacro [because they lack a sacred bard]. They are the episodes of that cyclic poem written by Time upon the memories of men.
