The group was discovered by
Hermann von Soden and designated by him with the symbol K1. Wisse included this group to the Kx (and Ki), and according to him it is the only subgroup or cluster of Kx. But the opinion of Wisse is based on a small sample size, only three chapters of Luke — chapters 1; 10; and 20. Based on age alone, it appears that K1 is independent of Kx. The leading members of the group, according to Soden, are manuscripts S, V, and Ω. According to Soden the group K1 is the oldest form of the Kappa–text, dating from the 4th century and resulting from
Lucian's recension. The texts of
Matthew 16:2b–3 (
the signs of the times),
Luke 22:43-44, John 5:3.4, and the
Pericope Adulterae (John 7:53–8:11) are marked with an
asterisk (※) as doubtful. The text of
Mark 16:8-20 has not numbered by (
chapters) at the margin and their (
titles) at the top. The group probably evolved from
Family E. It represents the earliest stage of the Kappa-text. == Members of the family ==
