recording Oedipus at colonus

Cassirer's version of Oedipus at Colonus is being digitised as an audio play, with help from a cast of local actors and the School of English Theatre Studies team. The Greek play was the last work of 5th century BCE playwright Sophocles. It imagines the final hours of Oedipus' life, exploring themes such as guilt, freedom, and fate. Cassirer's text was his last complete work and this is its first public outing. Learn more.
