Perhaps you should try some spelling variations:
epigrammaton » epigrammata, epigrammatum, epigrammatic
epigraph » epigraphy, epigraphic, epigram
epigramsies » epigrammes, epigraphies
digraphy » digraphs, tigraphy, epigraphy, digraphsy
digraph » digraphs

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: ((( epigrammaton OR epigrams ) OR epigraph ) OR ( epigramsies OR (digraphy OR digraph) )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((( epigrammaton or epigrams ) or epigraph ) or ( epigramsies or (digraphy OR digraph) ))".
• Adding a wildcard symbol may retrieve word variants: ((( epigrammaton or epigrams ) or epigraph ) or ( epigramsies or (digraphy OR digraph) ))*.
