British Museum - Ancient Egypt Writing

http://www.ancientegypt.co.uk/writing/rosetta.html

The above hyperlink leads to a site linked to the British Museum describing the Rosetta Stone.  The various points about the Rosetta Stone are divided into sections by questions asked about it.  The answers given are short but to the point, explaining what it is, its origins, why it is written in three different languages, and its general history.

Unfortunately, because the answers are so short that they do miss a number of details.  As an example, while they do explain that the Rosetta Stone was found in a town called Rashid (Rosetta, hence its name), and while it does explain he knew both Greek and Coptic, which helped him to decipher the manuscripts, it neglected to mention, unlike the video in my earlier blog, that Champollion also used the Philae Obelisk as a means to assist him in deciphering the Egyptian hieroglyphs.

So while the site does give straight-forward answers, the information is limited, and looking for sites with more in-depth analysis and description of both the history of the Rosetta Stone and of Champollion would be recommended.
