13.6 Impacts of Mining on Geomorphic Systems

“…At the time of Agricola's writing, 'metal' was more broadly interpreted to include a wide range of ore minerals. Bermannus was reprinted in 1546, along with four new papers on geology, in a treatise commonly referred to as the 'First Handbook of Modern Systematic Mineralogy,' which included De Ortu et Causis Subterraneorum and De Natura Fossilium (Agricola, 1546). In 1556, Agricola published his most influential work, De re Metallica (on the nature of minerals; Agricola, 1556).…”

Some early eighteenth century geological Materia Medica

“…(Leonardus 1502(Leonardus , 1750Agricola 1546;Lovell 1661;Agricola in Bandy & Bandy 1955; see Duffin 2008 for further details). Two of the most unusual means of administration must be with a poached egg in the treatment of hysterical fits, gonorrhoea and dysentery (Brookes 1763), and on a special toast as part of the treatment for leucorrhea ('the whites' or Fluor albus -a vaginal discharge that may be indicative of hormone imbalance, vaginal infection or vaginal and cervical inflammation: Wecker 1660).…”

“…This is a belief that extends back to the Greeks, who believed that the ailment was the consequence of upsetting the goddess Selene; Dioscorides records its use in cases of epilepsy (Dioscorides V, 141;Beck 2011, p. 400). Agricola (1546) states that 'fragments drunk in sour wine relieve dysentery', and that the powdered mineral, once burned and sprinkled on fistulas, causes regeneration of the flesh (Bandy & Bandy 1955, p. 93). Hill (1751, p. 250) notes that selenite is accredited as being 'a very powerful Astringent, and is of great Effect in Diarrhoeas, Dysenteries and haemorrhages of all kinds'.…”

“…10; Bostock & Riley 1857, p. 396) counted it as 'the very best cautery for the human body is a ball of crystal acted upon by the rays of the sun' according to contemporary medical men. Agricola (1546;Bandy & Bandy 1955, p. 120) notes that, finely ground and taken in sour wine, it stops dysentery, whilst Albertus Magnus indicates that the powder, when administered in honey to a post-partum mother, 'fills the breasts with milk' (Wyckoff 1967, p. 83).…”

First African diamonds discovered in Algeria by the ancient Arabo-Berbers: History and insight into the source rocks

“…Pliny, in particular, says in his Naturalis Historia (37.55) that the diamond existed in Ethiopia -that is, to the South of Egypt. It has also been reported that the Carthaginians exchanged precious stones, among which were diamonds, with the interior of Africa (e.g., Agricola, 1546;Heeren, 1799).…”
