ANCIENT WRITING IN PLAIN ENGLISH

Say it twice,
read it again.

A text you can read, next to the same text you cannot, is a key.

1 TEXT 3 scripts

1,600 Years the meaning of hieroglyphs was lost

Ancient rulers sometimes had one message carved in several languages so that more people could read it. Centuries later those repeated texts let scholars match known words against unknown signs and bring lost scripts back to life.

THE SHORT ANSWER

A known language
beside an unknown one.

Two inscriptions did for two lost scripts
what a dictionary does for us.

ROSETTA, 1799

Found in the Delta

The stone was found in 1799 at el-Rashid, known as Rosetta, in the western Nile Delta, carrying the same text in three scripts.

Compare the scripts

THE DECREE

Hieroglyphs, demotic, Greek

The text is a decree issued at Memphis in honour of Ptolemy V, dated to 27 March 196 BC. Greek, which scholars could read, gave the way in.

Who cracked it

BEHISTUN

A cliff in three languages

Darius I's great inscription in Old Persian, Elamite and Babylonian made it possible to decipher cuneiform.

Which script
are you reading?

Pick a script to see what part it plays. The bar shows how many lines of text survive on the Rosetta Stone, or on the Behistun cliff.

Script check

Choose a script
Hieroglyphic (Rosetta)14 lines

The script of Egyptian priests. None of the three texts on the stone is complete.

Demotic (Rosetta)32 lines

The script in common everyday use in Egypt at the time.

Greek (Rosetta)54 lines

The language of administration, and the one scholars could already read, which made it the starting point.

Old Persian, Elamite, Babylonian (Behistun)About 1,200 lines

Around the relief of Darius I run about 1,200 lines in three languages, describing his battles of 521 to 520 BC.

HOW A DUAL TEXT IS USED

Four steps from
known to unknown.

Decipherment took decades and many scholars, but the basic method is simple to follow.

  1. Read the known version

    Start with the script you understand, such as the Greek on the Rosetta Stone.

  2. Find the names

    Thomas Young was the first to identify hieroglyphs relating to the king named in the text, Ptolemy V.

  3. Work out reading direction

    Young also worked out which way the signs should be read.

  4. Test the system

    Champollion showed the signs were a mixture of alphabetic, syllabic and determinative elements.

TWO NUMBERS WORTH KNOWING

How long
lost writing waited.

One figure for how long hieroglyphs went unread,
one for the scale of the Behistun text.

1,600

Years the meaning of hieroglyphs was lost

Champollion's work in the early 1820s rediscovered the full significance of Egyptian hieroglyphs, lost for about 1,600 years, showing they mix alphabetic, syllabic and determinative signs.

HIEROGLYPHS · WORLD HISTORY ENCYCLOPEDIA

≈ 1,200

Lines of inscription around the relief

The inscription ordered by Darius I in 521 BC is written in three languages. Encyclopaedia Iranica calls it a key comparable to the Rosetta Stone for Egyptology.

BEHISTUN · UNESCO

Darius had the access path cut away after the work was finished, so until recently the inscriptions could be reached only by a steep and difficult climb up the rock face, Encyclopaedia Iranica notes.

WHO CRACKED IT

Many hands,
one breakthrough.

Scholars including de Sacy, Åkerblad and Thomas Young worked on the Rosetta text, with Young making significant progress. The French scholar Jean-François Champollion made the crucial breakthrough and described it in 1822 in his Lettre à M. Dacier.

The stone itself was found by an officer of engineers in Napoleon's army while an old wall was being demolished, and later passed to the British. It is now in the British Museum in London.

Questions

Questions people ask

What does the Rosetta Stone say?

It carries a decree issued at Memphis in honour of Ptolemy V, to be displayed in every temple in Egypt, dated to 27 March 196 BC. The same text appears in hieroglyphic, demotic and Greek.

Why was the Rosetta Stone so important?

Because it was quickly realised that the three versions recorded the same text. The readable Greek gave scholars a way into the Egyptian scripts.

Who deciphered hieroglyphs?

Several scholars contributed, including Thomas Young, but Jean-François Champollion made the crucial breakthrough, published in 1822.

What is the Behistun inscription?

A monumental relief of Darius I in western Iran surrounded by a great inscription in Old Persian, Elamite and Babylonian. It made the decipherment of cuneiform possible.

How big is the Rosetta Stone?

World History Encyclopedia gives 112.3 by 75.7 cm and 28.4 cm thick, with parts of the top corners and bottom right missing.
