Nipson anomēmata mē monan opsin

Nipson anomēmata mē monan opsin (Ancient Greek: Νίψον ἀνομήματα, μὴ μόναν ὄψιν), meaning "Wash the sins, not only the face",[2] or "Wash my transgressions, not only my face",[3] is a Greek palindrome[fn 1] that is said to be first inscribed upon a holy water font outside the Hagia Sophia in Constantinople:[4] The phrase is attributed to the fourth-century Saint Gregory of Nazianzus.

[3] 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 inscription can also be found in the following places:

ΝΙΨΟΝ ΑΝΟΜΗΜΑΤΑ ΜΗ ΜΟΝΑΝ ΟΨΙΝ (translation: Wash your sins, not only your face ) in the monastery of Panayia Malevi [ el ] . [ 1 ]
