Nvma is based on Roman letterforms which appeared during the period from the earliest extant examples in the sixth or seventh century BC until the end of the third century BC. For Nvma the J, U and W had to be fantasies as they did not exist until much later, similar to the G, numerals and other non-alphabetic signs in the font. Thus not all of the archaic forms are represented in Nvma. Nvma was designed to work with Magma, as it matches the weights and heights for Magma Thin and Magma Titling Thin.
