Which of the following empires had no written language?

How interesting that they had no written language, and they communicated through a series of knots!! Makes me wonder if they were very talkative or not – no pun intended

Sounds like a ropey old system but I suppose they could handle some quite knotty problems

so is it rude to say get knotted

They're showing Machu Pichu in the photo!

I am surprised that people picked Roman. Lingua Latina is the common language that influences the languages of the Western hemisphere. Of the English alphabet, remove the j (created in 16th century and adopted into Latin), the w, and the y (a Greek character adopted into Latin later during the Roman Empire, and that is the Classical Latin alphabet. Half of English words are created from Latin, including "created."

Trish, maybe they used a dot matrix printer to write notes

Nix, knot heads

The aztecs did not have their own script...
