A sequel to her widely used A Companion to Familia Romana (now in its second edition), Jeanne Marie Neumann's A Companion to Roma Aeterna offers a running commentary, in English, of the Latin grammar covered in Hans H. rberg's Roma Aeterna, and includes the complete text of the rberg ancillaries Grammatica Latina and LatinEnglish Vocabulary II. It also serves as a substitute for rberg's Instructions, on which it is based.
