—————————— to death's abode
Prone lies the path, and facile is the road.
To all who seek them open day and night,
Pluto's black gates with broad access invite.
But to recall the foot, retrace the way
Up the dark steep, and re-assert the day—
This is the labor, this the mighty feat,
Achieved by few, the greatest of the great.

Book VI, lines 185–192 - The Æneis (1817)
