anthony trollope wrote a "life of cicero"

Searching the Internet Archive to see what I could find of Cicero's writings, I discovered that Anthony Trollope (Wikipedia, handle with care) wrote a Life of Cicero in two volumes (Chapman and Hall, 1880):

• The life of Cicero (Volume 1)
• The life of Cicero (Volume 2)

Finding the time to browse through it is another thing . . .
