Once upon a time a museum in a charming old German town was given a very important, long-lost gravestone.

It was that of Maria Sophia von Erthal, a baroness who is believed to have inspired the Brothers Grimm to write Snow White and the Seven Dwarfs.

Her restored gravestone has just gone on display at the Diocesan Museum in Bamberg , southern Germany. It was donated by a family who had rescued it.

The museum director says Sophia's life "became the nucleus of Snow White".

The baroness grew up in a castle in Lohr am Main, about 100km (60 miles) west of Bamberg, in north Bavaria, and died in 1796.

"The story of Sophia's life was well known at the start of the 19th Century," museum director Holger Kempkens told the BBC.

The Snow White fairy tale, by Jacob and Wilhelm Grimm, was published in 1812 and reached global audiences when Walt Disney created the animated film in 1937, but there have been many other adaptations.

"The Brothers Grimm made literature out of the stories they heard from local people," Mr Kempkens said.

"There are indications - though we cannot prove it for sure - that Sophia was the model for Snow White. Today when you make a film about a historic person there is also fiction in it. So in this case I think there is a historic basis, but there are also fictional elements."

The much-loved Snow White tale has some famous elements:

a wicked stepmother who plots to kill Snow White out of jealousy

a magic mirror which answers "Snow White" when the stepmother asks: "Mirror, mirror on the wall, who is the fairest of them all?"

the stepmother's poisoned apple

the seven dwarfs who look after Snow White and work in a mine

a prince who finds Snow White in a glass coffin and rescues her.

The Brothers Grimm lived for a long time near Hanau, which is just 50km from Lohr am Main.

In the 1980s a local historian in Lohr, Dr Karlheinz Bartels, researched parallels between Sophia's life and the fairy tale, called Schneewittchen in German:

Sophia's father, a nobleman called Philipp Christoph von Erthal, remarried after his first wife's death, and Sophia's stepmother had the reputation of being domineering and acting in favour of her natural children

Lohr was a famous centre for glassware and mirrors. Sophia's father owned the mirror factory, and a museum in Lohr today proudly displays one of those mirrors with the inscription: "Amour propre" (French for "pride")

A scary forest features in the tale, and a forest near Lohr was notorious for robbers and dangerous wild animals

Snow White ran over seven hills before reaching the cottage inhabited by the seven dwarfs, who toiled in a mine; and a mine outside Lohr, now disused, can be reached by crossing seven hills

Dwarfs and/or children did indeed work in the mine, and wore cloaks as protection against falling stones and dirt.

Some significant parts of the tale were not derived from Sophia's life: the glass coffin (despite her father's glass business); the poisoned apple; the saviour prince.

Sophia's life did not have such a happy ending: she went blind in her youth and died unmarried in a convent, aged 71.

Mr Kempkens said the marble gravestone had a coating of chalk concealing the inscription, so it required careful restoration. The inscription says: "The noble heroine of Christianity: here she rests after the victory of Faith, ready for transfigured resurrection."

It is also historically significant because at that time women did not usually get their own gravestones.

Sophia's gravestone was originally in an old church in Bamberg which was knocked down, Mr Kempkens said.

The gravestone was then installed in a hospital, founded by a brother of Sophia. When a new clinic was built there in the 1970s the gravestone was removed and kept by a local family, who later donated it to the Bamberg museum.
