I was reading this book that I got earlier today called Ethiopic: The First Language by Ras Iadonis Tafari aka Wendim Yadon who heads the Lion of Judah Society.

What caught my eye while reading this book is when it introduced me to this fact that the Egyptian hieroglyphics were similar, and adopted by the Ethiopians. Here are some quotes from the book that prove this.

"In the 1886 AD Proceedings of the Canadian Institute, page 29, it is summarized that: 'From these facts it might be inferred a priori that there would be an essential resemblance between the Egyptian Hieroglyphic and Ethiopic, and this is true as a matter of fact'" pg. 99

"Diodorus, the Greek historian wrote, from BC times, concerning the ancient relationship and connection of the Ethiopic and the Hieroglyphs of Egypt that: 'The Ethiopians affirm that most of the Egyptian laws are the same with those in Ethiopia, the colony still observing the customs of their ancestors; and that they learnt from the Ethiopians to make statues, and the character of their letters. For, whereas the Egyptians have two sorts of characters, namely the ordinary characters used promiscuously by all the inhabitants, and those that which they call sacred, known only by the priests, yet the Ethiopians use both sort without any difference or distinction. The Ethiopic hieroglyphs represent the shapes of divers beasts; parts and members of human bodies, and artificers' tools and instruments. For, instead of expressing any thing by composition of syllables, they express it by images and metaphoric representations; the meaning of them being ingraven and fixed in memory by use and existence.'" pg. 102

There will be more discourse on it as I read more of it.
