There are also some translations, you can compare with this translation : http://books.google.fr/books?id=ThC5OoAisaMC&pg=PA21&lpg=PA2... of the same page: on the last line, page 21, you can read "Il cache à la fois le dieu des mers et cette faible mortelle" (It hides both the god of the sea and this weak mortal) and on the mystery document, left margin : "Il cache le dieu et la mortelle" (It hides both the god and the mortal). There are a few other plain Greek -> French translations.
I'm not sure if it's translation, but it's definitely at least transliteration. Χλωριν - Chlorin.
Which to me looks like a translitiration of the word that is underlined.
edit: translation -> translitiration
