On Gnosticism

Submitted by Halcyon In Kal… on 1 June 2013

Fascinating In Our Time episode on Gnosticism, The Gnostics divided the universe into two domains: the visible world and the spiritual one. They believed that a special sort of knowledge, or gnosis, would enable them to escape the evils of the physical world and allow them access to the higher spiritual realm. The Gnostics were regarded as heretics by many of the Christian Church Fathers, but their influence was important in defining the course of early Christianity. A major archaeological discovery in Egypt in the 1940s, when a large cache of Gnostic texts were found buried in an earthenware jar at Nag Hammadi, enabled scholars to learn considerably more about their beliefs.

On Simon & Garfunkel Halcyon In Kal… 26 September 2012

On September 19, 1981, Paul Simon and Art Garfunkel played in front of 500,000 people in Central Park, New York City.  I missed this concert by three days, as I had to end my first ever visit to the US to go back home to prepare for starting at Edinburgh University, but I saw them play much the same set live at Wembley Stadium the following June - a highly memorable experience even 30 years on.
