The curious typography of the legend seems to give the date: if the initial capitals "G" and "A" are ignored and the unneccessary capitals isolated (i.e. "GoDefrIDVs Abbas prVDentiâ fVLgens fLoreat! ViresCat!"), the numerical sequence 500, 1, 500, 5, 5, 500, 5, 50, 50, 5, 100 is produced. These figures added together give a date of 1721, an interesting example of information concealed cryptically within a dedication inscription.
