Analysis of The Marseillaise

What means this mighty chant, wherein its wail
Of some intolerable woe, grown strong
With sense of more intolerable wrong
Swells to a stern victorious march--a gale
Of vengeful wrath? What mean the faces pale,
The fierce resolve, the ecstatic pangs along
Life's fiery ways, the demon thoughts which throng
The gates of awe, when these wild notes assail
The sleeping of our souls ? Hear ye no more
Than the mad foam of revolution's leaven,
Than a roused people's throne-o'erwhelming tread?
Hark! 'tis man's spirit thundering on the shore
Of iron fate; the tramp of Titans dread,
Sworn to dethrone the Gods unjust from Heaven.
