From child to youth; from youth to arduous man;
From lethargy to fever of the heart;
From faithful life to dream-dowered days apart;
From trust to doubt; from doubt to brink of ban;—
Thus much of change in one swift cycle ran
Till now. Alas, the soul!—how soon must she
Accept her primal immortality,—
The flesh resume its dust whence it began?
O Lord of work and peace! O Lord of life!
O Lord, the awful Lord of will! though late,
Even yet renew this soul with duteous breath:
That when the peace is garnered in from strife,
The work retrieved, the will regenerate,
This soul may see thy face, O Lord of death!

Dante Gabriel Rossetti
