Lingua Latina is a complete immersion course providing Latin that students read and understand immediately. Every sentence is intelligible per se because the meaning and function of all new word forms is clear from the context, illustrations, or marginal notes throughout this carefully graded text. Part 1 (Familia Romana) is the eventful and entertaining story of a Roman family, which also serves as an introduction to the life and culture of ancient Rome. Part 2 (Roma Aeterna) tells Roman history from the beginnings. Students who have completed Part 1 are already able to read classical texts, such as Orberg's editions of Caesar's Gallic Wars or of Plautus' Amphitryo. In Part 2, students read extensive selections from classical authors, refine their knowledge of syntax, and develop a vocabulary of over 4000 words. Upon completion of the course, students can read the most challenging classical texts with relative ease.
