124 Irenaeus: Life, Scripture, Legacy
In Luke, only three Old Testament citations are marked,^46 all, though, with the
simple diple, in John only one (at 12:37-40), using the dotted diple. Despite the sparse-
ness and irregularity of the markings in the Gospels, beginning with the citation of
Psalm 69:26 in Acts 1:20, the rest of the codex, containing Acts, the Catholic Epistles,
the Pauline epistles (including Hebrews), Revelation and the two Clementine epistles
show a regular use of the “standard” form of marginal quotation diplai for scriptural
quotations, although 2 Clement does not have them.^47 The use or nonuse of the diplai
does not seem to distinguish the various scribes^48 but could be related to the underly-
ing textual complexions of the exemplars used, as I will note later.
