Sarah Williams' lyrics "Though my soul may set in silence" from her poem "The old Astronomer" was set to music with a nice melody, see [this YouTube video][1] for example.
The melody is attributed to Franz Joseph Haydn.

**Which Haydn piece was this meldoy taken from?**

Searching the web only resulted in sites that show the "Though my soul..." linked to Haydn, but without naming the underlying piece.
Searching the melody on [Musipedia.org][2] had no satisfying results either.

Is anyone more familiar with Haydn's work and recognises the melody?
