Gresham College Lectures

From 1600 – 1850, artists in England and, later, in North America depicted distinguished Native American tribal leaders, diplomats and warriors to commemorate their significance. Examples include Pocahontas (1617), and nineteenth century Lakota leaders Sitting Bull and Red Cloud.For many years, these portraits were not properly understood, reducing many of the sitters to simple exemplars of the ‘noble savage’ cliché. In fact, these works are far more interesting once the sitters’ historical situation and agency are restored to them.A lecture by Stephanie Pratt recorded on 28 March 2023 at Barnard's Inn Hall, London.The transcript and downloadable versions of the lecture are available from the Gresham College website: https://www.gresham.ac.uk/watch-now/american-portraitsGresham College has offered free public lectures for over 400 years, thanks to the generosity of our supporters.

We interface with our environment via the air we breathe, the food and water we eat and drink, and through physical contact via our skin.This lecture explores how these biological barriers act to protect us against toxins and toxicants, through an exploration of dose, detoxification and elimination mechanisms, antioxidant defences and innate immune mechanisms.A lecture by Dr Ian Mudway recorded on 27 March 2023 at Barnard's Inn Hall, London.The transcript and downloadable versions of the lecture are available from the Gresham College website: https://www.gresham.ac.uk/watch-now/interfaces-worldGresham College has offered free public lectures for over 400 years, thanks to the generosity of our supporters.

Every animal on the planet carries with it an astonishingly diverse microbial zoo – millions of invisible organisms that thrive on the skin and in the gut. They play an important role in health and disease and may also shape human emotions and behaviour. Viruses may stimulate aggression, parasites can trigger suicide and bacteria can block fear responses. The evidence for our interaction with microbes may even make us want to re-evaluate the concept of free-will.A lecture by Robin May recorded on 22 March 2023 at Barnard's Inn Hall, London.The transcript and downloadable versions of the lecture are available from the Gresham College website: https://www.gresham.ac.uk/watch-now/manipulate-lifeGresham College has offered free public lectures for over 400 years, thanks to the generosity of our supporters.

This talk will explore the potential for harnessing the public health framework for addressing online safety and security.Throughout the COVID pandemic, citizens have washed their hands, covered their faces, and maintained a physical distance. If members of the public can protect themselves and others from offline viruses, why not digital ones?A lecture by Victoria Baines recorded on 21 March 2023 at Barnard's Inn Hall, London.The transcript and downloadable versions of the lecture are available from the Gresham College website: https://www.gresham.ac.uk/watch-now/digital-pandemicGresham College has offered free public lectures for over 400 years, thanks to the generosity of our supporters.

In recent years, the links between sleep and mental health have been slowly unravelled. We are beginning to understand that not only does mental health impact sleep, but also that poor sleep has important consequences on our psychology.This lecture explores this complex relationship, and highlights the importance of sleep as a major factor in our mental wellbeing. The lecture covers strategies to manage disturbed sleep, and touches on other disorders such as nightmares and night eating syndrome.A lecture by Guy Leschziner recorded on 13 March 2023 at Barnard's Inn Hall, London.The transcript and downloadable versions of the lecture are available from the Gresham College website: https://www.gresham.ac.uk/watch-now/sleep-healthGresham College has offered free public lectures for over 400 years, thanks to the generosity of our supporters.

During the medieval ‘agricultural revolution’, new forms of cereal farming fuelled the exceptionally rapid growth of towns, markets and populations across much of Europe. The use of the mouldboard plough and systematic crop rotation were key developments and led to open-field farming, one of the transformative changes of the Middle Ages.Using new evidence from plant and animal remains from archaeological excavations in England, this lecture links these to wider developments in medieval society, notably growing social and wealth inequalities.A lecture by Helena Hamerow recorded on 23 March 2023 at Barnard's Inn Hall, London.The transcript and downloadable versions of the lecture are available from the Gresham College website: https://www.gresham.ac.uk/watch-now/agricultural-revGresham College has offered free public lectures for over 400 years, thanks to the generosity of our supporters.

We used to think Roman Britain was a largely untamed natural landscape of woodland with occasional opulent villas representing the houses of an alien elite, set side by side with scattered peasant settlements. Archaeological work since the 1940s has radically altered this understanding through a combination of large-scale excavation and a revolution in remote sensing techniques, revealing a more varied picture of housing, farming, settlement and industry.This lecture will explore our current knowledge of the nature of Roman imperialism and the history of Britain.A lecture by Martin Millett recorded on 15 March 2023 at Barnard's Inn Hall, London.The transcript and downloadable versions of the lecture are available from the Gresham College website: https://www.gresham.ac.uk/watch-now/roman-landscapesGresham College has offered free public lectures for over 400 years, thanks to the generosity of our supporters.

What is the adversarial tradition in English criminal and civil procedure, and how does it compare with the inquisitorial systems found in some civil law jurisdictions? What are the strengths and weaknesses of adversarial and inquisitorial jurisdictions? Does our adversarial system truly deliver equality of arms between the powerful and the powerless? Have modern fair trial standards, such as those required by the European Court of Human Rights, -and other developments - brought the two families of systems closer together?A lecture by Leslie Thomas KC recorded on 9 March 2023 at Barnard's Inn Hall, London.The transcript and downloadable versions of the lecture are available from the Gresham College website: https://www.gresham.ac.uk/watch-now/adversarial-lawGresham College has offered free public lectures for over 400 years, thanks to the generosity of our supporters.

What happens to carbon dioxide after we emit it? Half is absorbed within a year or two by plants and the oceans, the rest, in effect, stays in the atmosphere. So, does that mean we have to halve emissions to stop concentrations rising? Unfortunately, no.Despite the vast reserves of carbon dissolved in the oceans, carbon dioxide released by burning fossil fuels does not get diluted away, but makes an indelible mark on climate for hundreds of thousands of years.A lecture by Myles Allen recorded on 7 March 2023 at Barnard's Inn Hall, London.The transcript and downloadable versions of the lecture are available from the Gresham College website: https://www.gresham.ac.uk/watch-now/carbon-zeroGresham College has offered free public lectures for over 400 years, thanks to the generosity of our supporters.

The Norse and Danish invaders - commonly called Vikings - who occupied Britain in the ninth and tenth centuries, brought with them their own pagan gods. Odin, Thor, Tyr, Loki and Freya left their trace on the British landscape, in the form of scenes from their mythology carved on stone slabs, and Viking paganism has a further considerable legacy of material evidence in richly furnished graves, especially on the Isle of Man.A lecture by Ronald Hutton recorded on 8 March 2023 at David Game College, London.The transcript and downloadable versions of the lecture are available from the Gresham College website: https://www.gresham.ac.uk/watch-now/viking-godsGresham College has offered free public lectures for over 400 years, thanks to the generosity of our supporters.
