An SVG version of the University of Pennsylvania seal of 1894.  Based upon the image in (1894)  Catalogue of the University of Pennsylvania 1894-1895, Philadelphia:  University of Pennsylvania  OCLC:   183432992.  It contains the Latin phrase sine moribus vanæ, the motto of the university from 1756 to 1898.  It was intended to allude to a line from Horace's III.24 (Book 3, Ode 24), quid leges sine moribus vanæ proficiunt? ("of what avail empty laws without [good] morals?"). When it was pointed out that the motto could be translated as "Loose women without morals", the university quickly changed the motto to literæ sine moribus vanæ ("Letters without morals [are] useless"). In 1932, all elements of the seal were revised. As part of the redesign, it was decided that the new motto "mutilated" Horace, and it was changed to its present wording, Leges Sine Moribus Vanæ ("Laws without morals [are] useless").[1]  Made using Inkscape and Gimp.
