This essay presents the methods, as well as the pedagogical effects, findings and results of introducing Ancient Greek in the curriculum of children between three and 12 years old as evidenced over 27 years in the method of Elliniki Agogi. Elliniki Agogi is an award-winning private educational institute established in Greece in the mid-1990s at a time when the teaching of Ancient Greek was questioned and dramatically reduced from the public curriculum. Its aim is to safeguard learning that has its roots in Ancient Greek and to continue to introduce students to the Greek civilisation and its language, using effective, entertaining and artistic methods. This endeavour was based on specific pedagogical models; by learning through experience and through a communication-orientated educational process. With concomitant, cautious organisation and preparation of each lesson a diversified educational curriculum is created that connects the students to their distant past while experiencing positive emotions, filled with ethical paradigms that contribute later to master a fully-shaped personality. 27 years later, studies have come to prove the positive influence of learning Ancient Greek in children's linguistic and mental abilities. The following study conducted is distinctive in the detailed pedagogical method it provides and validates the importance of teaching the Ancient Greek language to children as early as possible.
