Hans Henning ørberg (1920--2010) received his MA in English, French, and Latin from the University of Copenhagen in 1946. He taught at various Danish high schools until 1963 and at the Grenaa Gymnasium until 1988. From 1953 to 1961 he served on the staff of the Nature Method Institute, Copenhagen. He is the author of the Latin course "Lingua Latina secundum naturae rationem explicata" (1955--56); the course was revised in 1990--91, with a number of supplements, under the title "Lingua Latina per se illustrata." His books were published by Domus Latina, a publishing house he founded in Denmark, and are distributed in the English speaking world by Focus Publishing.

"Jeanne Marie Neumann’s A Companion to Roma Aeterna provides students, instructors, and homeschoolers with a treasure trove of learning that will enable them to fully benefit from Ørberg’s absurdly underused Roma Aeterna." -- James Dobreff, Department of Classics & Religious Studies, UMass Boston

"In using ørberg's Roma Aeterna students undertake the daunting task of reading Latin containing advanced and complex grammatical concepts without the aid of any English explanations or assistance. Neumann's companion text regularly serves as a welcome relief and periodically as a necessary crutch in the task. Using the two texts in coordination with each other is a highly effective method for learning Latin, maximizing the strengths and minimizing the weaknesses of ørberg's "Natural Method." In the end it all boils down to this: Roma Aeterna will successfully teach students to read Latin, and Companion to Roma Aeterna will help those students understand the complex grammatical and syntactical concepts that underlie the Latin language." —Michael Holstead, in The NECTFL Review
