after feeding the text into a computer code breaking algorithm, the trio were amazed to spot a few words in French.

Those few words, which included “prochain” - next - “temps” - time - and “moins” - less - were able to give an indication of which symbols stood for certain letters, but the team quickly realised there was far more going on in the cipher.

For example, the discovery of a specific symbol had been used to signal that the previous letter should be repeated, while another was used when the previous letter should be deleted. A separate symbol indicated a full stop.

Different symbols had also been used for parts of words such as the “que” in catholiques (catholics) as well as the “ant” in advantage, and “ion” in “persecution”.

Frequently used words, such as king (roy), queen (royne), “monsieur” and “madame” all had their own symbols, while a capital “C” stood for the King of France, and a lower case “d” the King of Spain.

To make the code even more tricky there were interchangeable symbols for some vowels and consonants, as well as separate symbols for nouns such as names or months.

Mary, who was born in 1842, became Queen of Scotland at just six days old, but was sent to France when she was six and was brought up in the French court, eventually marrying the Dauphin Francis.

Although Francis became king, he died within a year of taking the throne and Mary moved back to Scotland. Following the death of her second husband, nobles turned against her and she was forced to flee to England where she was imprisoned by Elizabeth I who feared she would try to take the throne.

Descended from Henry VIII’s sister, Mary had a claim to the English throne, and many Catholics believed she was the legitimate queen, not recognising the marriage between Henry and Anne Boleyn, Elizabeth’s mother.

Viewed as too great a threat, she was imprisoned for 19 years, and eventually put to death aged 44 in 1887 for her part in an alleged plot to kill Elizabeth.
