Does “Roman numerals” need a capital letter?

[reallyneedmoresleep]

Hello wise pedants. I’m struggling to find agreement on this elsewhere on the web. Clearly, if I’m writing about the Romans I capitalise the R but what about if I’m referring to Roman numerals? Or a Roman soldier? ( interestingly, autocorrect wants to capitalise all of them). Thanks for any answers

No. Romans does, but not numeral or soldier.

Thanks Little Candle. So presumably "arabic numerals" doesn't need a capital A either?

Of course you capitalize Roman and Arabic in whatever context you use them! Would you write “a french soldier” or (if they existed) “french numerals” or “french cuisine”? No.

Yup - capitals all the way.

Yes to capital R

Capitals

Always a capital except in roman à clef.

Or, I've just discovered, a pink or red sea bream.
