Plaque Description

The Dexter Award plaque consists of 4 parts:

  1. A felt backed wooden board painted black 12" x 9"
  2. Using a bronze mold a pewter plate 3.5" x 3" is cast.

    The design, in relief, is a copy of the design on the frontispiece of the Plicto de Larte de Tentori che Insegna Tenger Pani Telle Banbasi et Sede si per Larthe Magiore come per las Comune by Gioanuentura Rosetti, published in Venice in 1548. Sidney M. Edelstein and Hector C. Borghetty published a translation of the 1548 edition (The Plichto of Gioaventura Rosetti Instructions in the Art of the Dyers which Teaches the Dyeing of Woolen Cloths, Linens, Cottons, and Silk by the Great Art as Well as by the Common MIT Press, 1969). In the Introduction they state "Rosetti's Plichto is the first basic printed book on dyeing."

    Frontispiece from Plichto(1548)
    showing only the relevant image

    As to what the figures in the image represent, one can only speculate as Edelstein and Borghetty did not address this point. The three-faced figure is likely time - past, present, and future. The words are Tempus (Latin time), Giugus (this is not Latin, but might be Latin spelled the way Italians spoke the word. If so, this could be GIUDicia, therfore iugum, meaning yoke, burden, or obligation. Italian for yoke is giogo), Aura (Latin breeze, wind, heaven), and Domat (from Latin for dominus, "a lord"). What does that all mean? Literally, it could be "Time overcomes a/the yoke/burden with (the help of) a breeze." Or it might not. Intentional ambiguities many times abound concerning this type of art. [Thanks to Bruce Swann and Alvan Bregman of the University of Illinois Library for help in the translation.]

    This image does not appear to be a printer's mark (the printer of the 1548 edition was Augustino Bindoni). It is possible that the image is a coat of arms or armorial device connected to a dyers guild, but there is no evidence to support that statement.

  3. A pewter plate 5” x .625’ x .093”. The name of the award is hand engraved on it.
  4. A pewter plate 4” x 4.5” x .125” hand engraved with the recipient’s name and an explanation of the nature of the award and the name of the presenter.

Sidney Edelstein wished that the award look old fashioned hence the handwork. No machine engraving is used.
