And if I laugh at any mortal thing,
'T is that I may not weep; and if I weep,
'T is 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           her mortal son in Styx;
A mortal mother would on Lethe fix.
