The 30-second version

In 1799 a slab was dug up near Rosetta carrying one decree in three scripts, and nobody could read two of them. The first foothold was tiny: royal names sealed inside oval rings called cartouches.

Two names that share letters make a built-in check, because a sign appearing in both must carry the same sound. Read Ptolemy's ring, then use those signs to unlock Cleopatra's, as Champollion did on the road to 1822.
