"The National Archives (UK) holds possibly the greatest collection of untapped source material for heralds and heraldry in this country. This lecture examines evidence stretching back over eight and a half centuries: seals, illuminated manuscripts, medieval rolls, treaties, grants of arms, state occasions, architectural drawings, military badges and even wooden chests. The result is an astonishing and colourful display of what is often unknown heraldic material. Adrian Ailes is a Principal Records Specialist at The National Archives and in 1997 organised an exhibition on Heraldry in the Public Records. He is a Fellow of the Heraldry Society and an academician of the Academie internationale d'héraldique"
