§ 69.15–23, 71.1–3 · 0/12 in the cited books
Roman History 70.1 is itself the witness to a loss: 'It should be noted that the account of Antoninus Pius is not found in the copies of Dio, probably because the books have met with some accident'《罗马史》70.1本身即为亡佚的见证：“须注意，狄奥抄本中不见安敦尼·庇乌斯部分，大约因卷帙遭遇损毁”
Provenance: “primary source” = curated canonical witness (editorial); “dated witness” = derived from the ToposText date index by year-span, with the matched loci count. Sparse counts may include incidental mentions.出处：「源典」为校订之正典见证（编辑判断）；「系年见证」由 ToposText 系年索引按年代跨度推得，附匹配条目数；稀少者或含偶涉。
