Family K<sup>1</sup> is a small group of the New Testament manuscripts. It belongs to the Byzantine text-type as one of the textual families of this group. It has five uncials, and several early minuscules. It is one of the smallest subfamilies of the Byzantine text-type, but one of the oldest.
The group was discovered by Hermann von Soden and designated by him with the symbol K<sup>1</sup>. Wisse included this group to the K<sup>x</sup> (and K<sup>i</sup>), and according to him it is the only subgroup or cluster of K<sup>x</sup>. But the opinion of Wisse is based on a small sample size, only three chapters of Luke â chapters 1; 10; and 20. Based on age alone, it appears that K<sup>1</sup> is independent of K<sup>x</sup>. The leading members of the group, according to Soden, are manuscripts S, V, and é.
According to Soden the group K<sup>1</sup> is the oldest form of the KappaâÂÂtext, dating from the 4th century and resulting from Lucian's recension.
The texts of (the signs of the times), Luke 22:43-44, John 5:3.4, and the Pericope Adulterae (John 7:53âÂÂ8:11) are marked with an asterisk (â») 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.
