A Secret Code at Shugborough Hall?

A well known monument at Shugborough Hall, Shropshire, U.K., preserves a marble reproduction by Peter Scheemakers of Nicolas Poussin’s famous painting “Les Bergers d’Arcadie”. Below the engraving appear the letters O U O S V A V V together with A and and O at either end, slightly lowered. Whereas professional cryptographers have treated these letters as a secret code, they are best interpreted as standard abbreviations of common Latin words that might be expanded as follows: D(is) M(anibus) O(ptimae) U(xoris) O(ssa) S(ita) V(ices) A(gens) V(t) V(overat) or V(otum) A(nimo) V(t) V(overat) The possibility remains that the Anson brothers, on whose estate the monument stands, were involved in secret societies.
