Some people may know about Comenius' Latin picture books of the world, but few know about adaptations of his Orbis Pictus series into ancient Greek.
John Amos Comenius ( March 28, 1592 – November 15, 1670) was a European Educator from Moravia, who wrote an important series of school textbooks for learning Latin. These were textbooks covering the complete curriculum, as he devised it. The textbooks were written in Latin, and come in a gradated series. The aim of these textbooks was to get the students to become fluent in Latin, as school was taught in Latin - but the textbooks were not all LATIN textbooks, but general schoolbooks, covering the subjects we now recognise as history, politics, the sciences, &c.The goal of learning Latin was combined with general scholarship, so the reader was not just learning the language, but useful information about the world as well, at the same time.
