The following patristocrat-style cryptogram has been found among the notes of a group of professional thieves. The plaintext was destroyed, except for the last two words: "museum artifacts." Please try to recover the plaintext, if you can. The ciphertext has the letters grouped into sets of five, for ease of transmission
Good luck!
