A disputed early use of the smiley in a printed text may have been in Robert Herrick's poem "To Fortune" (1648), which contains the line "Upon my ruins (smiling yet :)". Journalist Levi Stahl has suggested that this may have been an intentional "orthographic joke", while this occurrence is likely merely the colon placed inside parentheses rather than outside of them as is standard typographic practice today: "(smiling yet):". There are citations of similar punctuation in a non-humorous context, even within Herrick's own work. It is likely that the parenthesis was added later by modern editors.
