Rational Recreations, Plate III
Download full-size image

Description: 

“Plate III” features four illustrations of rational recreations involving optics and illusions. Figure 1 illustrates the refraction of light through water in a vessel. Figure 2 diagrams alterations in human vision based on the optic nerve receptors. Figure 3 is a portable camera obscura much like the one illustrated by Guyot in Nouvelles récréations. Figure 4 is a magic lantern.

Printing Context

“Plate III” appears in William Hooper's original edition of Rational Recreations, Volume II.

Associated Texts

Rational Recreations was corrected and reprinted in a second edition (1782-1783), and later in a fourth edition (1794). Hooper takes several of his optical recreations from earlier editions of M. Guyot’s Nouvelles récréations physiques et mathématiques (1772-1775) (Hooper 19).

Subject

“Plate III” features four illustrations of rational recreations involving optics and illusions, including the refraction of light through water, alterations in human vision based on the optic nerve receptors, a portable camera obscura, and a magic lantern. The plate accompanies instructions in the text describing how to create these optical devices and illusions.

Significance

The connection between M. Guyot’s Nouvelles recreations of 1772 and Hooper’s subsequent Rational Recreations is clearly stated in the latter author’s text and is “indicative of the later eighteenth-century tendency to publish in multiples” for particularly popular genres (Stafford 58). Hooper credits Guyot with the invention of the portable camera obscura (Figure 3), and copies the illustration of the elegant, furniture-like design from the French author almost exactly (Hooper 28). The table-like camera obscura, with the lens and mirrors hidden beneath the projection surface, evokes Barbara Maria Stafford’s conception of “furniture-to-think-with,” drawing room pieces constructed to be useful for both socialization and education in the Romantic period (Stafford, “Revealing Technologies/Magical Domains” 11). The side table style apparatus challenges Jonathan Crary’s argument that the camera obscura serves to interiorize or decorporealize vision by isolating the viewer within the apparatus. Although composed of the same basic elements as other types of camera obscura—including the focusing lens, glass mirror, and glass pane—camera-obscura-as-furniture quite literally becomes a parlor trick for group entertainment, rather than a space of isolated viewing (Crary 39).


Unlike some texts on rational recreations from this period, Hooper emphasizes the re-creative imaging potentials of the camera obscura, writing that the apparatus “affords the most perfect model for painters, as well for the tone of colors, as that degradation of shades, occasioned by the interpolation of the air, which has been so justly expressed by some modern painters” (Hooper 24). In re-creating Guyot’s original text on scientific recreations, Hooper not only reiterates the correlation between optics and illusions but also maintains the continuity of the forms and subjects of inquiry begun in the Enlightenment and carried into the Romantic period.

Function

Hooper's text and its images describe how to create optical instruments for recreational scientific experiments.
