The experimental lesson in the first year of high school dealt with phraseologisms from Greek mythology. We combined Serbian and Latin and gained new knowledge about Greek heroes. Achaeans are not to be trusted when they bring gifts. We were able to overcome the only week spot, Achilles’ heel, with new insight and knowledge. The entire story seemed at the beginning as Sisyphus’ boulder, but we were saved by Ariadne’s thread from Tantal’s misfortune and fear that we would not be able to absorb the knowledge at hand. We did not allow our differences to become the apple of discord. As Prometheus took fire, we acquired knowledge here that as fire will illuminate our way. The class was organized by teachers Katarina Urošević and Milena Pavlović, and lit up by Vuk Puzović and Nikša Balaban.
