Music and theatre in Handel's world : the family papers of James Harris 1732-1780
James Harris (1709-80) was an author of philosophical treatises and an enthusiastic amateur musician who directed the concerts and music festivals at Salisbury for nearly fifty years. His family and social circle had close connections with London's music-making: his brother was a witness to Handel's will, and his correspondents sent him lively reports on all aspects of musical life in the capital-opera, oratorio, concerts, but also about the leading performers, music copyists, and instrument makers. In 1761 Harris became a member of Parliament and thereafter divided his time between London and Salisbury. His letters and diaries provide an unrivalled record of concert- and theatre-going in London, including exchanges of letters with David Garrick about a production at Drury Lane. As his children grew up an engaging family correspondence emerged. We learn of his daughters' involvement in concerts and amateur theatrical productions; his son, who pursued a diplomatic career, reported on operas, concerts, and plays in the court of Frederick the Great and Catherine the Great. Now, for the first time, it is possible to enjoy in full the lively first-hand descriptions from Harris's family papers, which contribute fascinating insights into contemporary eighteenth-century musical and theatrical life
Positive Sulfate Sulfur Isotope Excursion Indicates Large-Scale Pyrite Burial and Marine Anoxia during the End–Triassic Mass Extinction
The late Rhaetian–early Hettangian transition is
characterised by the emplacement of Central Atlantic
magmatic province and associated climatic effects, coincident
with a severe biotic crisis (~201.5 Ma). The oxygen
deficiency in the ocean realm is possibly linked to this
significant loss in marine biodiversity. However, direct
evidence of contemporaneous development of marine anoxia
on a global scale has been lacking and the relationship
between oxygen and extinction is unclear. Here we report
carbonate-associated sulfate δ34S data from three sections
across the Late Triassic–Early Jurassic transition. We find
synchronous large positive δ34S shifts with a magnitude of
>10‰ in the latest Rhaetian at all three locations. The
duration of the shift is estimated to take as little as ~50 Kyrs.
Biogeochemical modelling suggests that this positive Sisotope excursion reflects a global increase in pyrite burial by
approximately five times, consistent with broadly correlative
records for development of marine anoxia on the Panthalassa
margin and NW European shelf. This shift in pyrite burial
and inferred ocean deoxygenation also correlate with the
major phase of the extinction. Our modelling results suggest
that sulfate-poor conditions (<1 mM) are established prior to
the pyrite burial event in the Late Triassic, which also
characterizes many other oceanic anoxic events (OAEs)
during the late Permian and the rest of the Mesozoic Era.
Here we also propose a conceptual model that low sulfate
conditions may have been a prerequisite to enhance net
benthic methane release to the water column and places an
increased burden on the bottom-water oxygen levels during
these OAE
