05/09/26-Faith & Fire Discovery Day : Science, history and faith meet in the footsteps of Samuel Pepys
A huge thank you to everyone who joined us on Saturday 5th September for our Faith & Fire Discovery Day, marking the anniversary of the Great Fire of London, 360 years ago.
Across St Olave Hart Street, Seething Lane Gardens and All Hallows by the Tower, hundreds of visitors followed in the footsteps of Samuel Pepys and explored the Great Fire from some very different perspectives.
Professor Guillermo Rein and the Hazelab team from Imperial College London brought fire science dramatically to life with live experiments in Seething Lane Gardens, on the site of Pepys’ home, One experiment used a ‘dragon’ to mimic the ‘firedrops’ which Pepys recorded raining down on London. In both churches, children and adults explored Pepys’ eyewitness account of the Great Fire, tried writing in the shorthand he used for his diary, dressed up in Restoration style, investigated how and why fires behave as they do, and reflected on the many different meanings of fire in the Bible and Christian tradition.
But the day was also about the present.
What can the Great Fire teach us about the wildfires experienced by communities around the world today? How can science help us understand fire and protect lives? What helps communities recover after disaster? And what might faith contribute to questions of resilience, responsibility and hope?
St Olave’s survived the Great Fire of 1666 and is the perfect setting to discover that science and faith need not be competing explanations of our world: together they can help us understand it, respond to it and ask what kind of future we want to build.
Our enormous thanks to Professor Rein and Hazelab; our friends at All Hallows by the Tower; everyone who volunteered, demonstrated, welcomed, photographed, walked, talked, experimented, wrote, drew, prayed and took part; and especially to the Scientists in Congregations programme, run by ECLAS, whose generous grant made the project possible.
The flames of 1666 have long gone. The questions they leave behind are still very much alive.
