When the sentence is rendered in capital letters, as would be usual for an inscription (ΝΙΨΟΝΑΝΟΜΗΜΑΤΑΜΗΜΟΝΑΝΟΨΙΝ), all the letters are vertically symmetrical except for the Ν. As a result, if the N is stylized Ͷ in the right half (ΝΙΨΟΝΑΝΟΜΗΜΑΤΑΜΗΜΟͶΑͶΟΨΙͶ). The sentence is not only a palindrome but also a mirror
ambigram.
^The
romanization is not a palindrome because the Greek letter ψ (
psi) is transcribed by the
digraphps. The modern
diacritics, which are not symmetrical, are usually omitted from inscriptions of the sentence.
