Graeca is a way to write Latin with the Greek alphabet devised by Malcolm Lutz. He wondered what it would be like if the Romans had used the Greek alphabet for their language instead the Latin alphabet. He based it on the Ancient Greek alphabet.
Ομνεσ ηομινεσ διγνιτατε ετ υουε λιβερι ετ παρεσ νασκουντουρ, ρατιονισ κονσκιεντιαυ παρτισπεσ σουντ, κϝουιβουσ ιντερ σε κονκορδιαυ στουδιο εστ αγενδουμ.
Omnes homines dignitate et iure liberi et pares nascuntur, rationis et conscientiae participes sunt, quibus inter se concordiae studio est agendum.
All human beings are born free and equal in dignity and rights. They
are endowed with reason and conscience and should act towards one another
in a spirit of brotherhood.
