And if I laugh at any mortal thing,
’Tis that I may not weep; and if I weep,
’Tis that our nature cannot always bring
Itself to apathy, for we must steep
Our hearts first in the depths of Lethe’s spring,
Ere what we least wish to behold will sleep:
Thetis baptized her mortal son in Styx;
A mortal mother would on Lethe fix.
