Passage: The original catalyst for development was the ill-fated vanity project by Lord Kensington (died 1852) which consisted of the two-mile conversion of the insanitary Counter's Creek into the Kensington Canal (1826 onwards), followed by its eventual replacement first by "Mr Punch's railway", opened in 1844 and next, by the Metropolitan District Railway in 1865–69, which eventually became London Underground's District Line and was joined after 1907 by the Piccadilly line. Meanwhile, the congestion apparent in London and Middlesex for burials at the start of the century was causing public concern not least on health grounds. In 1837 a decision was made to lay out a new burial ground on the edge of Earl's Court in an outlying area of Brompton. The moving spirit behind the project was the engineer, Stephen Geary. It was necessary to form a company in order to get parliamentary permission to raise capital for the proposal. Securing the land – some 40 acres – from local landowner, Lord Kensington and the Equitable Gas Light Company, as well as raising the money proved an extended challenge. After two years the cemetery was duly established by Act of Parliament and laid out in 1839, it opened in 1840, originally as the West of London and Westminster Cemetery. It was consecrated by Charles James Blomfield, Bishop of London in June 1840, and is now one of Britain's oldest and most distinguished garden cemeteries, served by the adjacent West Brompton station.

Passage: Antonio Denzio (23 September 1689 – after 1763) was an Italian impresario, tenor, and librettist. Born in Venice to a family of musicians and operatic personnel, he pursued a career mainly as a singer until 1724, when he traveled to Bohemia as a member of the opera company of Antonio Maria Peruzzi, probably his uncle. Peruzzi had the idea of bringing an Italian opera company to central Europe to perform first in Prague, then Dresden and Leipzig. The company was first brought to Bohemia under the patronage of Count Franz Anton von Sporck, who had it play at his palace at Kuks in northwest Bohemia in the summer of 1724. The performances were so successful that he permitted the company to perform free of charge in his palace in Prague. After disagreements with Peruzzi, Denzio was able to supplant him as impresario before the end of the year 1724 and continued productions in the Sporck palace until 1735. Peruzzi left with some of the Peruzzi-Denzio players to found the Breslau Opera. Denzio's opera theater at Sporck's palace was the first standing opera theater in the city. His productions were popular with the Bohemian nobility until about 1729, after which Denzio's finances deteriorated. Count Sporck provided no financial assistance to the company except the free use of his theater, and he allowed it to fail. The company went bankrupt and Denzio was forced to spend time in debtors' prison. During its heyday, Denzio was able to attract at least one of the principal singing stars in Italy to Prague each season. The most prominent of all was Margherita Gualandi, who was forced to come to Prague after being blackballed in Italy for bad behavior. Denzio sought the assistance of Antonio Vivaldi in engaging singers for his company, and the composer sent music. In the early 1730s, Vivaldi came himself to Prague. Some of the music for one of his operas composed for Prague, Argippo, has only recently been re-discovered.
