The Rosetta Stone: one decree, three scripts
One decree was written in three scripts. How did comparison help people read Egyptian writing, and why was the stone not a ready-made dictionary?

What survives on the stone
The British Museum records a decree written on the Rosetta Stone in hieroglyphic, Demotic, and Greek scripts. Its collection record dates the object to 196 BCE. British Museum ↗
Why comparison matters
Because scholars could read Greek, the parallel inscriptions helped them investigate the Egyptian writing. The stone became an important part of decipherment, rather than a self-contained dictionary. British Museum ↗
What can you see on the stone?
Open the collection record and separate the object's date, inscription, and later history. Ask which details are directly visible and which depend on translation or comparison. That distinction is useful whenever a historical claim starts with a text.
Reading without a parallel text
What would you need to interpret an inscription without a parallel text? Think about repeated signs, names, context, and other witnesses before proposing a reading.
