Two royal cartouches spell names you already know from the Greek register — Ptolemy and Cleopatra. Drag a sound tile onto a glyph to guess its value; every correct match locks that sign in everywhere and quietly decodes the rest of the stone, exactly the way Champollion cracked the script in 1822.

Why it matters
Why explore this?
History is about change over time and the choices that shape it. This model helps you compare causes, consequences, and patterns without treating the past as a list of dates.

Questions to test
Predict first, try it in the model, then use what you observe to answer.
What to try
- The lion glyph sits in both Ptolemy and Cleopatra. If it is L in one name, what must it be in the other?
- Which single glyph, once solved, reveals the most words elsewhere on the stone?
- Turn off the Greek register. Can you still bootstrap an alphabet using only the overlap between the two cartouches?
- Two tiles in the tray never fit anywhere. Why would a real decipherer expect sounds that the Greek names simply do not contain?
- After solving M, I, S and R the word MIṢR appears — the Egyptians' own name for Egypt. What does it tell you that a hidden word was readable all along?
Explain
Make sense of what happened
Build an explanation with a cause, a change, and a consequence. Then identify evidence from the model and one limitation of what the model can show.

What can this model not tell us?
If you can answer all three using evidence from the model, you understand the main idea. If not, return to Explore and change one setting at a time.
