Read this excerpt from The Riddle of the Rosetta Stone by James Cross Giblin. Champollion's contributions to the world's knowledge of ancient Egypt did not end with his death, however. Working
from Champollion's notes, his brother Jacques-Joseph completed the Egyptian Grammar and Egyptian Dictionary
that Champollion had started. The books were published in several volumes during the 1830s and 1840s, and were
warmly welcomed by most scholars in France, Germany, England, and other countries.
