Getting Started with… Middle Egyptian by Patrick J. Burns.
Middle Egyptian, sometimes referred to as Classical Egyptian, refers to the language spoken at Egypt from the beginning of the second millennium BCE to roughly 1300 BCE, or midway through the New Kingdom. It is also the written, hieroglyphic language of this period and so the medium in which the classical Egyptian literature of this period is transmitted. Funerary inscriptions, wisdom texts, heroic narratives like the “Tale of Sinuhe” or the “Shipwrecked Sailor,” and religious hymns have all come down to us in Middle Egyptian hieroglyphic. We also have papyri from this period written in a cursive script known as hieratic. The “middle” separates this phase of the Egyptian language from that of the previous millennium, or Old Egyptian (for example, the “pyramid” texts), and Late Egyptian, which begins in the second half of the New Kingdom and lasts until roughly 700 BCE with the emergence of Demotic. …
It’s been years since I seriously looked at a Middle Egyptian grammar or text but as a hobby, you could do far worse.
For hackers it offers the potential to keep records only you can read.
I don’t mean illegible, we can all do that, but written in a meaningful script but decodeable only by you.
Even better, you can take known religious texts, quotations for your notes. Various law enforcement agencies can hire (hope they charge top dollar) experts to translate your notes. Standard Middle Egyptian religious texts. Maybe that’s your thing. No way to prove otherwise.
The other upside is your support for the publishing of Middle Egyptian grammars, readers, and payments to Middle Egyptian experts by authorities for translation of standard texts. Bes will see the humor in such payments.
Enjoy!
