If, for fun, you want to make it look like an inscription, then use all caps, don’t use U or J, don’t use spaces (use medial dots instead, or nothing), don’t use macrons (you can use apices if the vowel length seems really important to you), don’t use punctuation, etc.

FORTUNE FAVOURS THE BOLD

“Fortune favours the bold“, “Fortune favours the brave“, “Fortune helps the brave“, and “Fortune favours the strong” are common translations of the Latin proverbs:

• Audentes Fortuna Iuvat (present participle of the verb audeo, to dare), literally: “Fortune helps those daring”
• Audentes Fortuna Adiuvat, literally: Fortune comes to the aid of those daring
• Fortuna Audaces Iuvat (from the adjective audax, audacis, from the verb audeo), literally: “Fortune helps the bold”.
