Capitalization of Adjective from Proper Noun

Question

As the title of a piece of music, I am trying to translate the words 'Oedipal Eucharist' into Latin, with appropriate capitalization. I have:

Eucharistia oedipal

1. Am I correct that it is 'Eucharistia' and not 'Eucharistica'?

2. Am I correct that as a Latin adjective, the word 'oedipal' needs to appear without a capital 'O' ([i ]even though this is the title of a piece of music, and [ii] as in the way that in French, the adjective 'français' appears with a lower-case 'f'.

Thank you for your advice.

Answer 1

1. You are correct.

2. There is no word oedipal in Latin. If you want an adjective from Oedipus' name, you would use Oedipodionia. It is in fact customary to capitalize adjectives derived from proper nouns, as editors regularly do for this word.
