In engineering, Schott diagrams are the illustrations of the vacuum and electrostatic experiments undertaken by Otto Guericke, in the 1650s, as published by the efforts of Gaspar Schott, in his 1657 Mechanics of Gas Hydraulics and later in the 1672 Otto Guericke’s New Experiments on the Magdeburg Vacuum Space, generally detailing Guericke’s quest to make an artificial vacuum, so as to publicly disprove Aristotle's, i.e. Parmenides’ 485BC postulate, that vacuums are an impossibility in nature; the diagrams are shown below: [1]

Seems to be a depiction of Guericke's electrostatic generator?

A depiction of Guericke trying to evacuate the air form a well-caulked beer keg, which introduced him to the sealing problem, i.e. how to make a container air tight. Guericke Beer keg color. (Ѻ) A depiction of Guericke working on the "sealing problem" with his invention of the two hemispheres in place of the beer keg. Guericke test two color. (Ѻ) Guericke vacuum experiments (1654) color. (Ѻ)

Diagram likely depicting Guericke’s success “at emptying glass vessels of their contained air by sucking it out at the mouth of the vessel, plunged under water”, the bucket being the water. [2]
Double bulb color. (Ѻ)

Guericke weighing color. (Ѻ) From Schott (1664). [4] (Ѻ)

Fig. 2: The gas test with the cylinder approximately 1659 (after [7]). [3]
Possibly a depiction of Guericke’s work on the barometer applied to weather prediction? Picture 1: Otto von Guericke (center) with his Magdeburg Halbkugetn. Modern painting according to historical documents in the entrance hall of the Physikalisches Instituu of the Friedrich-Schiller-Universittl Jena. (Taken from Mus. Phys. 15 (1959) No. 9, p. 404.) [3]
