This return to the classroom looks and feels like the first day of school. Just like September, all teachers and students are masked; arrows indicate traffic flow directions through the school’s central cortiles and down each hallway. Standing in the Cortile, one can hear snippets of the City of Rome class, Inge Weustink introducing the new unit on “Sustainable Cultural Heritage,” and the beginning of an IB Environmental Systems and Society class, Jan Claus Di Blasio explaining the difference between climate and weather. During classes, when the Cortile’s benches stand empty, voices continue to fill this open space, as each classroom door and all windows remain open throughout the day, facilitating the constant circulation of fresh air. Every so often, a stray student or teacher emerges from a classroom, bundled in a puffy coat, wool scarf, and knit hat. Just before lunchtime, a gregarious, energetic group of Latin I students rushes through the Cortile, hurrying to make it in time for the departure of their field trip to decipher ancient Latin inscriptions at the Aventine Hill churches of Santa Prisca and Santa Sabina.
