Ancient Greek literature
Seven works of Sophocles have survived, the most acclaimed of which are the three Theban plays, which center around the story of Oedipus and his offspring. The Theban Trilogy consists of "Oedipus the King", "Oedipus at Colonus", and "Antigone". Although the plays are often called a "trilogy," they were actually written many years apart. "Antigone", the last of the three plays sequentially, was actually first to be written, having been composed in 441 BC, towards the beginning of Sophocles's career. "Oedipus the King", the most famous of the three, was written around 429 BC at the midpoint of Sophocles's career. "Oedipus at Colonus", the second of the three plays chronologically, was actually Sophocles's last play and was performed in 401 BC, after Sophocles's death.
Antigono
Antigono is an 18th-century Italian opera in 3 acts by the Czech composer Josef Mysliveček composed to a libretto by the Italian poet Metastasio first produced in 1744 with music of Johann Adolf Hasse. This opera (and all the rest of Mysliveček's operas) belong to the serious type in Italian language referred to as "opera seria". For a performance in the 1780s, it would only be expected that a libretto by Metastasio would be abbreviated and altered to suit contemporary operatic taste. The cuts and changes in the text made for the performance of Mysliveček's version are not attributable.
