Saturday, September 20 was a dramatic day for the city of Larissa in central Greece. After 2,500 years of inactivity, its ancient Greek theatre was once again opened to spectators. In honor of the archaeologist Athanasios Tziafalias, chorals from the “Electra” of Euripides were presented under the directorship of Kostas Tsianos, in collaboration with the Lyceum Club of Greek Women of Larissa and the choir of the Municipal Conservatory. The performance coincided with Diazoma’s Seventh General Assembly of the Movement for the Ancient Theaters. The Larissa theater is thought to have been constructed in the third century BC. It served a dual purpose, hosting theatrical performances as well as assemblies of the local governing body, the so-called “Koinon of the Thessalians.” Following the Roman conquest of Greece, it was converted into an arena. Until recently, the greater part of the theater lay under private homes. Owing to the work of Larissa archaeologists, its marble seating and rich decoration has now been uncovered in its entirety.
