The inscription reads: Inventas vitam iuvat excoluisse per artes loosely translated "And they who bettered life on earth by their newly found mastery." (Word for word: inventions enhance life which is beautified through art.) The words are taken from Vergilius Aeneid, the 6th song, verse 663; Lo, God-loved poets, men who spake things worthy Phoebus' heart; and they who bettered life on earth by new-found mastery The name of the laureate is engraved on the plate below the figures, and the text "REG. UNIVERSITAS MED. CHIR. CAROL." stands for the Karolinska Institute. The Nobel Medal for Physiology or Medicine was designed by Erik Lindberg.
