Nothing is said of the manner of Caesar's coming into Rome after passing the Rubicon; nothing of the manner of fighting at Dyrrachium and Pharsalia; very little of the death of Pompey; nothing of Caesar's delay in Egypt.

The letters deal with Cicero's personal doings and thoughts, and with the politics of Rome as a city.
The passage to which allusion is made occurs in the life of Atticus, ca.

xvi: "Quae qui legat non multum desideret historiam contextam illorum temporum." [138] Jean George Greefe was a German, who spent his life as a professor at Leyden, and, among other classical labors, arranged and edited the letters of Cicero.

He died in 1703.
[139] It must be explained, however, that continued research and increased knowledge have caused the order of the letters, and the dates assigned to them, to be altered from time to time; and, though much has been done to achieve accuracy, more remains to be done.

In my references to the letters I at first gave them, both to the arrangement made by Graevius and to the numbers assigned in the edition I am using; but I have found that the numbers would only mislead, as no numbering has been yet adopted as fixed.
