A tablet discovered this year, suggests that Neo-Babylonians may have been the first to start writing break up letters.

King Nabonidus wasn’t a fan of being stood up, says a new finding by archeologists at Liberty University. Researchers have unveiled that the 6th-century BCE Neo-Babylonian king sent what is thought to be the first break-up letter ever discovered.

Largely believed to be the first figure in world history to commission archaeological work, the new finding points out that there is still a great deal to be discovered about Nabonidus’s reign.

The tablet begins, “News has reached me via the Upper Euphrates that you were visiting with my childhood friend Nisaba. I am devastated by this betrayal, as you are one of my favorite concubines. You have until the end of the month to pick up your flax shawls and sandals or else I will donate them to the temple of the moon god.”

The message was revealed after close analysis by the archeologists who first discovered the tablet late last year in southern Iraq.
