- Roger Godberd was a thug and arsonist who led a band of highwaymen who robbed wealthy travellers
 
Half covered in moss and with no headstone, this Warwickshire grave gives no sign of its importance.
But an historian has claimed this is the grave of one of the most famous men in English folklore.
This, he says, is the final resting place of Robin Hood.
David  Baldwin claims it is the grave of Roger Godberd, and it was he - a 13th  century farmer who committed burglaries, arson and murder - who became  the basis for the Robin Hood legend.
Mr Baldwin's book claims that a stone coffin in Loxley, Warwickshire, belongs to Roger Godberd, who he has unmasked as the real Robin Hood
Godberd's name has previously been put forward as the outlaw's true identity, and Baldwin now says that all the evidence points to this being accurate.
His list of crimes would certainly make him fit the idealised description of the legend.
Godberd  was a real-life outlaw who robbed the rich and was even captured by the  Sheriff of Nottingham and held in Nottingham Castle for his crimes.
He  led a band of merry men who ambushed wealthy travellers across Sherwood  Forest and was even helped by a friendly knight who helped him evade  the law.
Historians have spent years trying to identify Robin  Hood - even using medieval court papers - but Mr Baldwin has claimed to  have finally solved the mystery after decades of research.
He has written a book setting out the evidence in favour of his claim that Godberd was Robin Hood.
According  to his research, Godberd lived from the early 1230s to the 1290s and  was accused of an array of crimes across the country.
He led a gang of outlaws, believed to be responsible for assaults on travellers and churchmen, as well as burglaries, arson and even murder.

Medieval court documents show that his band of men ranged across Leicestershire, Nottinghamshire and Wiltshire terrorising the wealthy and that he was eventually imprisoned for his crimes.
He was even accused of  poaching deer in Sherwood Forest along with his companion Walter Devyas -  believed to be the Little John of popular legend.
Mr Baldwin,  a 64-year-old retired university lecturer and author from Leicester,  said: 'The story of Robin Hood is a mystery which has captured people's  imaginations.
'Some of the individuals who have been  identified as Robin in the past have something to be said for them but  none are entirely convincing.
'Robin Hood is a composite  character in that stories told of other outlaws have been borrowed over  the years and added to his legend.
'There are probably several outlaws whose deeds have contributed to the modern-day stories of Robin Hood.

'But I believe there is one man whose career underpins the stories.  His name is Roger Godberd and he was an outlaw who was active in the  late 1260s.
'Quite a number of his activities seem to be replicated in the stories found in the earliest Robin Hood ballads.
'He poached deer in Sherwood Forest, was captured by the Sheriff of Nottingham, was imprisoned in Nottingham Castle and had the assistance of a friendly knight who helped him stay one step ahead of the law.
'He certainly robbed churchmen, just as the legendary Robin Hood did.
'The similarities in the surviving stories about them suggest that one character could be based on the other.
'It  has been claimed that the legendary Robin Hood figure lived as early as  the reign of Richard the Lionheart and as late as that of Edward II - a  period of up to 140 years.

'But Walter Bower, one of the earliest writers to mention Robin Hood,  says that he was forced into outlawry after being involved in Simon De  Montfort's rebellion in the 1260s.
'Roger Godberd was one of Simon de Montfort's supporters which ties in with this very well.
'His name has been mentioned in some of earlier books about Robin, but the evidence has never been fully examined before.'
After evading the authorities for years, Godberd was eventually captured in the early 1270s and jailed.
But he was pardoned at his trial at the Tower of London and returned to his farm where he lived until his death.

The legend of Robin Hood has captured the imagination of film producers, TV writers and authors for decades.
The  earliest ballads written about the folk figure date back to 1450, while  film studios have recreated the legend countless times since the first  Robin Hood film feature in 1922.
In recent years, Kevin Costner's 1991 Robin Hood: Prince of Thieves earned Oscar and Golden Globe nominations.
Several  TV shows and even a Disney animated version appeared later, before  2010's most recent reincarnation starring Russell Crowe in the lead  role.
Mr Baldwin said: 'I believe Godberd's career inspired  some of the early ballads, and I hope the book will encourage people to  re-examine what they believe they know about Robin Hood.'
