From the German of P. Neumann

μάλα γέ τοι τὸ μεγάλας ὑγεΐας
ἀκόρεστον τέρμα, νόσος γὰρ ἀεὶ
γείτων ὁμότοιχος ἐρείδει.

Æsch., Ag.

Two chambers hath the heart:
There dwelling
Live Joy and Pain apart.

Is Joy in one awake?
Then only
Doth Pain his slumber take.

Joy, in thine hour, refrain—
Speak softly,
Lest thou awaken Pain.
