Too many to count.
On paper Gibbon's prose can appear dauntingly monumental, but David Timson's reading makes it come alive. You feel almost as if Gibbon were chatting with you. An absolutely marvelous job!
Again, too many to count.
Unfortunately Audible has adopted a policy of appending the Amazon.com reviews as a default if there are no reviews of the audiobook they are trying to sell. In the case of Gibbon, this means that anyone curious about this audiobook found himself wading through one-star reviews of a defective ebook version of Gibbon. So pay no attention to the Amazon.com reviews. The Naxos Gibbon is one of the great achievements of the "audible age," thanks to incredible reading of David Timson. (His Dickens is also wonderful.)
