Biography:
Originally trained as a geologist, Chris Duffin spent most of his working life as a High School teacher in south London. Following a Ph.D.
in Vertebrate Palaeontology at University College London in 1980, he has
published extensively (over 160 papers) on a wide range of fossil groups
including crocodiles, lizards and barnacles, but is particularly concerned with
sharks and their allies. He recently co-authored the Handbook of
Paleoichthyology Volume 3D . Chondrichthyes. Paleozoic Elasmobranchii : Teeth
(2010, Friedrich Pfeil Verlag). The history of Geology is a relatively recent
interest and has borne fruit in a Special Publication
of the Geological Society of London entitled A History of Geology and Medicine
(Duffin, Moody & Gardner-Thorpe 2013). Chris received the Palaeontological
Association’s Mary Anning Award for outstanding contributions to
palaeontology in 2011 and is currently a Scientific Associate at the Natural
History Museum in London.
A History of Geological
Therapies
Virtually
every culture in the world has made use of geological materials to treat their
sick. These geopharmaceuticals often supposedly acted by sympathy,
transference or natural magnetic powers. This lecture will examine the ways in
which a variety of rocks, minerals, fossils and earths were employed by healers
and apothecaries from the second millennium BCE to around 1750, taking into account Babylonian, Assyrian, Egyptian,
Roman, medieval Arabic, Chinese and Western practices, based both upon
artefacts and written accounts. Lapis lazuli, for example, was used to treat
eye conditions and tinnitus by the Assyrians, and used in specialized cosmetic
and medicinal kohls by the Egyptians. Various clays, mostly from the
Mediterranean area, were worked into small cakes and their provenance authenticated with symbols; these terra sigillata were used
extensively to treat digestive disorders and as ingredients in a wide range of
medicines used against all sorts of diseases. Even precious stones utilized in
the war against ill health. A well-stocked geological collection could provide
medicaments for an enormous diversity of ailments.
