What does nor and relise under someone in this sentence mean?
I don't understand this phrase at all,are these typos?
For example,
"Long before the ancient Egyptians tried to conquer the desert. But the construction of a waterway failed; the canal silted up. Nor was this ambitious project realized under Napoleon. His surveyors, after making some miscalculations, deemed the project unfeasible."
Is "nor" in this context mean, the construction of a waterway was not ambitious project that made Napolean realize???
Thank you
