In bod is Elizabeth Carter’s untranslated Greek epigraph to Ode to Melancholy, from Sophocles’ tragedy Ajax; omitted from your edition of the poem
O darkness, now my daylight,
O gloom of Erebus, for me
the brightest light there is,
take me, take me now
to live with you.* Take me,
a man no longer worthy to seek help
from families of gods or men, 470 
those creatures of a day.
For Zeus’ daughter, brave Athena,
abuses and destroys me.
Where can one escape?
Where could I go and rest?
If my past fame has been cut down,
along with these dead beasts beside me,
then, my friends, if I now seek
a madman’s triumphs, all the army,
with repeated blows from their own swords 480
will cut me down as well.
