The plates of Leupold's theatrum machinarum are somehow different. Gone is the tight aherence to "one plate, one machine." On many pages we find a great number of concepts and ideas smeared onto one page. This transition in format may have something to do with the sources upon which Leupold depended.
We know that he ransacked earlier machine works. He also borrowed ideas from Acta Eruditorum. His jumbled plates may be representative of the formatting styles of the early journals such as the Philosophical Transactions, Acta Eruditorum, or the Journal des Savants.
