\subsection{G.P. Harsd\"{o}rfer}

Georg Philipp Harsd\"{o}rffer (1607\EnDash{}1658), German poet, was born at Nuremberg. He studied law at Altdorf and Strassburg, and subsequently traveled through the Netherlands, England, France and Italy. His knowledge of languages gained for him the appellation ``the learned''. His writings in German and Latin fill fifty volumes.

In 1636 he published (along with Schwenter) a work entitled \Title{De\-i\-ci\-ae physi\-co-math\-e\-matic\-ae} \footnote{\BrHarsdoerfferQYEY{}}\EmDash{}which consists of 3 volumes of mathematical and physics curiosities (as in 'parlor tricks'), observations on music and poetry, designs for curious machines, observations on biology, etc. He also describes how to make ``a merry wine-music'':

Like Kircher, Harsd\"{o}rffer's assertions about 'a half-empty glass and a completely empty glass make an octave\ldots' are simply wrong. (Try it!) And there still isn't any suggestion of tuning the glasses in such a way that a melody can be played.

Harsd\"{o}rffer also describes an experiment reminiscent of Kircher's 5 glasses.\footnote{\BrHarsdoerfferQYEY{}, 2:488}

Harsd\"{o}rffer also describes a curious experiment involving supporting a wooden rod with a glass at each end and striking the rod in the middle, and observes that the glasses break less easily when there is water in them.\footnote{\BrHarsdoerfferQYEY{}, 2:411ff.}
