Abraham Yohannan, was born in the village of Digala in 1853. In 1886 he came to the United States to help prepare the revision of the Bible in Assyrian. He stayed to pursue studies at the General Theological Seminary and was later ordained a priest in the Episcopal Church. From 1894 to 1925 he was also an instructor and later a professor in the Oriental Department at Columbia University. This volume reproduces two smaller works he published during his long and fruitful career. The first book is a Modern Assyrian Ð English Dictionary. Unfortunately only the first letter of the alphabet (Alap) was published. Although no more was published, it remains unknown if he completed the rest of the dictionary. The second book is a translation into Modern Assyrian of the ÒBook of the Pearl on the Truth of ChristianityÓ by Mar Audisho (d. 1318). This book was printed by Samuel A. Jacobs in New York in 1916 and is an excellent example of early Assyrian printing in the United States using Linotype.
