A man has been jailed for three years after stealing a “historically unique” 350-year-old map worth £6,000 from the National Maritime Museum in Greenwich.
Melvin West, 70, cut the rare chart out of an atlas dating back to 1684 using a Stanley knife in the museum’s Caird Library, Woolwich Crown Court heard on Thursday.
Damian Warburton, prosecuting, told the court: “The completed atlas was valued at around £50,000, with the stolen map worth £6,000 alone on the black market.”
Police were alerted to the theft on 26 February last year after staff discovered a knife in the viewing room and noticed the map was missing. West, from Chingford in east London, was arrested on 4 March, but the map has never been recovered.
The court heard West had previously viewed the atlas on three occasions, including the day before the theft. He pleaded guilty at Bromley Magistrates’ Court to theft, criminal damage and possession of a bladed article.
Jessica Flain, defending, said West had partially paid someone to restore the map but had been unable to retrieve it because of unpaid fees.
Judge Charlotte Welsh rejected a request to delay sentencing and told West he had “led this court, the police and the museum a merry dance about the whereabouts of this item.”
She sentenced him to three years in prison for criminal damage, with concurrent terms of 16 months for theft and six months for possession of a blade.
In a statement, the museum said the loss of the map “undermines its bibliographical integrity” and prompted a costly security review of its reading rooms.
The theft has cast fresh light on the vulnerability of centuries-old documents held in public collections. Atlases printed in the 1680s belong to a golden age of cartography, when sea charts were engraved by hand and bound into volumes that survive in only a handful of copies. Curators say the removal of a single leaf from such a book destroys its completeness as a historical record — which is why the museum described the loss in terms of the atlas’s “bibliographical integrity” rather than simply its market value.
Library thefts are a recurring problem for national collections. Unlike gallery artworks, maps and prints sit in reading rooms where researchers handle them directly, and institutions rely on a balance of trust and supervision. Museums across London have tightened their reading-room security in recent years, introducing lockers, CCTV and page-by-page checks, and several have faced similar incidents — from hate-crime investigations handled by local courts to high-profile criminal cases in south London.
West’s sentence also reflects how seriously the courts treat blade offences combined with property crime. Possession of a bladed article in a public place carries up to four years in prison, and judges frequently impose substantial terms where the blade is used to facilitate another offence — as happened here with the criminal damage to the atlas. The three-year headline sentence puts this theft among the more severe custodial terms handed down for a heritage crime in recent years, and Greenwich will be watching whether the missing map ever resurfaces.
The Caird Library holds one of the world’s largest maritime archive collections, with manuscripts, charts and rare books spanning centuries of seafaring history. Researchers travel from around the globe to study its holdings, which is why the museum’s description of the loss as a blow to “bibliographical integrity” matters: a chart cut from its atlas is not merely a missing £6,000 object, but a gap in a record of how the world was once understood. The court also heard West had visited the atlas three times before the theft, including the day before — suggesting the plan was formed over weeks of apparent scholarly study.
Detectives continue to appeal for information about the whereabouts of the map.
