Question: The album "Lost Horizons" by Abney Park is influenced by which subgenre of science fiction that incorporates technology and 19th century steam powered machinery?

Context paragraphs:
List of steampunk works: Steampunk is a subgenre of fantasy and speculative fiction that came into prominence in the 1980s and early 1990s.  The term denotes works set in an era or world wherein steam power is still widely used—usually the 19th century, and often set in Victorian era England—but with prominent elements of either science fiction or fantasy, such as fictional technological inventions like those found in the works of H. G. Wells and Jules Verne, or real technological developments like the computer occurring at an earlier date.  Other examples of steampunk contain alternate history-style presentations of "the path not taken" of such technology as dirigibles or analog computers; these frequently are presented in an idealized light, or with a presumption of functionality.

Lost Horizons (Abney Park album): Lost Horizons is the 8th studio album by Abney Park, subtitled "The Continuing Adventures of Abney Park".  It is the band's first Steampunk themed album.

W. &amp; A. Fletcher Company: W. & A. Fletcher Co. was an American manufacturer of marine boilers and steam engines for steamboats on the Hudson, in the Great Lakes, Long Island Sound, and elsewhere in the late 19th and early 20th centuries.  The company was founded in 1853 and associated with development of steam powered ships from the original crude efforts.

Seventy-four (ship): The "seventy-four" was a type of two-decked sailing ship of the line which nominally carried 74 guns.  It was developed by the French navy in the 1740s and spread to the British Royal Navy where it was classed as third rate.  From here, it spread to the Spanish, Dutch, Danish and Russian navies.  The design was considered a good balance between firepower and sailing qualities, but more importantly, it was an appealing ideal for naval administrators and bureaucrats.  Seventy-fours became a mainstay of the world's fleets into the early 19th century when they began to be supplanted by new designs and by the introduction of steam powered ironclads.

The Steam Man of the Prairies: The Steam Man of the Prairies by Edward S. Ellis was the first U.S. science fiction dime novel and archetype of the Frank Reade series.  It is one of the earliest examples of the so-called "Edisonade" genre.  Ellis was a prolific 19th century author best known as a historian and biographer and a source of early heroic frontier tales in the style of James Fenimore Cooper.  This novel may be inspired by the steam powered invention of Zadoc Dederick.  The original novel was reissued six times from 1868 to 1904.  A copy of the first 1868 printing with its cover intact is owned by the Rosenbach Museum and Library, Philadelphia.

John Jay (builder): John Jay (1805–72) was a building contractor and, earlier, a skilled stonemason, who owned a construction company located in the central City of London within Metropolitan London, England, during the 19th century and its period of rapid civic and railway expansion in the middle of the 19th century.  Jay's varied body of works included building the Victorian clock tower and city clock of the British Houses of Parliament after the Westminster Palace had been damaged by a fire in 1833 fire.  Jay was also responsible for the construction of many smaller architectural projects, such as the notable Abney Park Chapel and the Trinity Independent Chapel.

Abney Park: Abney Park is situated in Stoke Newington, London, England.  It is a 13ha (32 acre) park dating from just before 1700, named after Lady Mary Abney and associated with Dr Isaac Watts, who laid out an arboretum.  In the early 18th century, the park was accessed via the frontages and gardens of two large mansions — her own manor house (Abney House), and the neighbouring Fleetwood House.  Both mansions fronted onto Church Street in what was then a quiet Nonconformist village.  In 1840 the grounds were turned into Abney Park Cemetery, where 200 000 people were buried.  Abney Park now serves mainly as a nature reserve.

Shand Mason: Shand Mason was a British company which designed and manufactured steam powered fire engines and other fire-fighting equipment during the 19th century and early 20th centuries.

Geneva steam bicycle: The Geneva steam bicycle was a steam powered motorcycle made by the Geneva Cycle Company, Geneva, Ohio in the United States in the late 19th century, in 1896.  An example was displayed at "The Art of the Motorcycle" exhibit created by the Guggenheim Museum.  The naptha-fired steam engine is based on a design by Lucius Copeland.

Steampunk: Steampunk is a subgenre of science fiction or science fantasy that incorporates technology and aesthetic designs inspired by 19th-century industrial steam-powered machinery.  Although its literary origins are sometimes associated with the cyberpunk genre, steampunk works are often set in an alternative history of the 19th century's British Victorian era or American "Wild West", in a post-apocalyptic future during which steam power has maintained mainstream usage, or in a fantasy world that similarly employs steam power.  However, steampunk and Neo-Victorian are different in that the Neo-Victorian movement does not extrapolate on technology and embraces the positive aspects of the Victorian era's culture and philosophy.
