We're often asked, "what were you on?" when we decoded the secret meanings to the profuse ellipses in an obscure novel from the 1920s.  (We compiled our surprising findings into Annotated Ellipses: Revealing A Hidden Dot-To-Dot Game Within A Novelist's Eccentric Punctuation.)  Well, the answer isn't so much what we took in but rather what we put on: special eyewear from the year 1623, as described in Uso de los Antoios para Todo Genero de Vistas.  Here's an illustration from the book, showing how the glasses focus upon rows of dots.  Here also is another illustration from the book, rather accurately showing the wearer's view of the world.
