The Hymnographic Book of Tropologion

The Tropologion is considered the earliest known extant chant book from the early Christian world which was in use until the twelfth century. The study of this book is still in its infancy. It has generally been believed that the book has survived in Georgian translation under the name ‘ladgari’ but similar books have been discovered in Greek, Syriac and Armenian. All the copies clearly show that the spread and the use of the book were much greater than we had previously assumed and the Georgian ladgari is only one of its many versions.
