medieval-religion: Scholarly discussions of medieval religion and culture There is a body of studies on this subject but these papers are not in the journals we usually study. They are in journals which specifically relate to Carbon-14 dating. Numerous scientists have used tree rings, one ring equals one year. The rings are of various thicknesses because of the weather in any given year. The rings of a living species of tree can be correlated to the rings of a dead sample of the same species from the same climatic area. Thus core samples from trees which live to be very old, such as the American Sequoia give us a gauge to determine the age of a dead piece of wood from nearby and of the same species. This age can then be matched against the Carbon 14 date. A lot of this work has been done particularly to verify Carbon 14 dates. I don't have a link to a good introductory article on the subject, but Dr. Henry Michael of the University of Pennsylvania did a lot of this work and his obituary explains it briefly. http://www.nytimes.com/2006/02/25/us/henry-michael-92-archaeology-groundbreaker-dies.html On Sat, Oct 21, 2017 at 2:22 PM, Madeleine Gray < [log in to unmask]> wrote: > medieval-religion: Scholarly discussions of medieval religion and culture > > Well, there's always dendro dating (not sure any surviving relic of the > True Cross would be big enough) > > Maddy > --- > Prof. Madeleine Gray > University of South Wales > http://www.heritagetortoise.co.uk > http://twitter.com/heritagepilgrim > 'Lle taw Duw nid doeth yngan' (St Fagan, allegedly) > > > On 21/10/2017 18:00, Marjorie Burghart wrote: > > medieval-religion: Scholarly discussions of medieval religion and culture > > Dear Martin, > Well, we did not understand the question in the same way then :) > I think the point of the original question was what people make of hard > science "evidence" in the particular context where it goes against what > they want to believe (especially given George's examples about relics of > the True Cross). > Best regards, Marjorie > > > > ----- Mail original ----- > De: "Martin Wallace" <[log in to unmask]> > À: [log in to unmask] > Envoyé: Samedi 21 Octobre 2017 19:37:47 > Objet: Re: [M-R] carbon dating of dated medieval objects > > medieval-religion: Scholarly discussions of medieval religion and culture > > Ah, but the Shroud is not a "dated" object, that is, one of which the age > was known with relative certainty before carbon dating.
