Friedrich Rückert (1788-1866), Professor of Oriental Literature in Berlin, wrote verses in memory of his friend Joseph Kopp:—

“How shall I know myself without thee,

Who knew myself as part of thee?

I only know one half is vanished,

And half alone is left, of me.

Never again my proper mind

I’ll know; for thee I’ll never find.

Never again, out there in space,

I’ll find thee; but here, deep within.

I see, tho’ not in dreams, thy face;
