Plate III — The Complaint
Three thousand seven hundred and seventy-six years ago, somebody bought bad copper.
Tell Ea-nāṣir: Nanni sends the following message. When you came, you said to me as follows: "I will give fine quality copper ingots." You left then but you did not do what you promised me.

Nanni's letter survived because it was pressed into wet clay and then, by accident, baked when the merchant's house burned down. The complaint outlived the merchant, the city, and the language. The wedges are still legible. The app teaches you to read them.
