The New Testament in Koine Greek, based on Tischendorf's 8th edition. Constantinus Tischendorf is perhaps best known for his discovery of the Codex Sinaiticus (one of the oldest extant copies of the New Testament in Greek, circa 360 A.D.) in a monastery at the foot of Mount Sinai. Tischendorf devoted his life to locating the most accurate sources for the compilation of the Greek New Testament. This desire for the earliest, most reliable manuscripts drove him for most of his life. The result of this drive is Tischendorf's Eighth Edition Greek New Testament, completed just two years prior to his death, and considered by many to be his best.
