The story of The Tripods is a variation on post-apocalyptic literature.

In the year 2100, the world is controlled by machines called Tripods.

Will, a thirteen year old living in the small ( fictional ) English village of Wherton, is looking forward to the transition to adulthood which will take place on the next " Capping Day ", until a chance meeting with a mysterious Vagrant named Ozymandias sends him on a quest to discover a world beyond the Tripods ' control.

The winners are taken by Tripods, which they discover to be machines operated by living creatures, to the Tripod city, which is located in a sealed, pressurized dome that sits astride a river.

The cult of the Tripods is strong in the Middle East ; the Masters via the Caps have replaced Islam by a religion worshipping the Tripods, with some similar features.

When the Tripods Came is a prequel written twenty years after the publication of the original " trilogy ", and set in the late twentieth century.

Like the narrator of the original trilogy, the narrator of When the Tripods Came is a young English boy, known as Laurie.

However, it turns out that this seemingly kind woman is actually quite mad, seeing Fizzio as a replacement for her own daughter who was taken by the Tripods years before.

* When the London Dome is breached, the sound of the alarms is described as " ulla, ulla, ulla ", which is the cry of the Martian Tripods in The War of the Worlds.

In the TV series adaption of The Tripods, filmed in 1983, the run-down Whiteleys building is used to portray an abandoned department store in 21st century Paris.

The interior of the machines is organic, with no windows or controls, as these Tripods travel at will.

Additionally, the tripods have another tentacle used as a pipette to drain human blood, which is then sprayed from the Tripods ' heads as fertilizer to aid the spread of the red weed.

The captured humans that get sucked into the Tripods could very well have their blood drained in the machine by a process that is a more " direct " form of blood drain.

As they used it on London after one of their Tripods is brought down by a Twelve-pounder, it may be seen as a reserve weapon in case the humans prove dangerous.

Examples of life under alien occupation can be seen in the TV series V, Falling Skies, John Christopher's book series, The Tripods, the comic book miniseries Slash Maraud, and the Half-Life and Resistance video game series.

Series one of The Tripods, broadcast in 1984, which had 13 half-hour episodes written by the well-known author of many radio plays Alick Rowe, covers the first book, The White Mountains ; the 12-episode second series ( 1985 ) covers The City of Gold and Lead.

Sam Youd ( 16 April 1922 – 3 February 2012 ), known professionally as Christopher Samuel Youd, was a British author, best known for his science fiction writings under the pseudonym John Christopher, including the novel The Death of Grass and the young adult novel series The Tripods.

The 1980s British television series based on his trilogy, The Tripods, was filmed near his house.

When the BBC made the television series of The Tripods in the ' 80s they departed from Christopher's description.

The Tripods was later made into a BBC TV serial, which ran for two series but was cancelled before the three-part story was completed.

His other television credits include Compact ( 1962 ), Paul Temple ( 1970-1971 ), Z-Cars ( 1971-1978 ), Poldark ( 1975 ), The Onedin Line ( 1977 ), All Creatures Great and Small ( 1978-1980 ), Juliet Bravo ( 1980 ), Dramarama ( 1983 ) and other science fiction series ', Out of the Unknown ( 1965 ), Moonbase 3 ( 1973 ) and The Tripods ( 1984 ).

Will returns to the headquarters of the Resistance after several months in the City of Gold and Lead, where he and Fritz ( who has escaped the city some time after Will and found his way back to the Resistance ) travel to Eastern Europe, the Caucasus region, and the Middle East and set up resistance cells with young boys who question the power of the Tripods.

* In John Christopher's 1967-68 trilogy of novels The Tripods, an alien race known as " the Masters " live in three huge, domed arcologies built on Earth to use as a base from which to colonise the planet.

The BBC adapted novels such as The Day of the Triffids ( 1981 ), The Invisible Man ( 1984 ), The Nightmare Man ( 1981, from the novel Child of the Vodyanoi ) and The Tripods ( 1984 – 85 ), which however remained unfinished.

The Resistance now charges Will, Beanpole and a German boy, Fritz, now wearing realistic-looking yet harmless caps, to infiltrate a Tripod city by competing in a regional sporting exhibition: the winners of the events are always offered to the Tripods for service.

The television version of The Tripods was jointly produced by the BBC in the United Kingdom and the Seven Network in Australia.

Tripods frequently are mentioned by Homer as prizes in athletic games and as complimentary gifts ; in later times, highly decorated and bearing inscriptions, they served the same purpose.

Tripods have the disadvantage of being heavy and bulky although they can be used with large equipment.

Tripods are generally restricted to heavier weapons where the weight would be an encumbrance.

Tripods are used for both motion and still photography to prevent camera movement and provide stability.
