What is a good font for a tattoo in Latin?

The most appropriate font for Latin tattoos is any of those that have the appearance of engraved lettering: good fonts to try first are Castellar, Engravers MT and Perpetua Titling MT. Latin phrases should typically be printed in capitals, and one should take care to ensure that 'u' as well as 'v' appears in capitals as 'V', not 'U'. It is worth contacting a professional Latin translation website for further information and ideas, like Classical Turns (http://www.classicalturns.com).
