Asomtavruli ( Georgian : ასომთავრული ) is the oldest Georgian script . The name Asomtavruli mean " capital letters " , from aso ( ასო ) " letter " and mtavari ( მთავარი ) " principal / head " . It is also known as Mrgvlovani ( Georgian : მრგვლოვანი ) " rounded " , from mrgvali ( მრგვალი ) " round " , so named because of its round letter shapes . Despite its name , this " capital " script is unicameral , just like the modern Georgian script , Mkhedruli .
