Come with prong, and come with fork,
Like the devil of their talk,
And with wildly rattling sound,
Prowl the desert rocks around!
Screechowl, owl,
Join in chorus with our howl!
(The First Walpurgis-Night, Johann Wolfgang von Goethe, publ. 1843)
There are also tuning forks used by Charles Darwin for experiments with spiders.
