This novel of imperial Rome comes at the era from a refreshingly different perspective, as a memoir dictated by a now largely forgotten but, in his own day, highly successful Alexandrian Jew, Tiberius Julius Alexander, whose status as both outsider and insider among the Roman elite, and whose estrangement from his own native culture, shapes his view of the world. Tiberius is both alienated from his world and integral to it; this is the stuff of good novels.
The author is clearly a competent and experienced wordsmith, but his previous expertise has been in the field of nonfiction. Fiction is a different art, and he makes some typical beginner's mistakes. The most jarring, and one that should have been mitigated by a good editor, is his inclusion of an intelligence report (see page 140) to convey certain personal information to the narrator; this device is very clumsy and not even remotely believable. The episode could possibly have worked by having Tiberius interview his agent and indirectly solicit the information, but in this form the agent's report stops the novel in its tracks.
A mixed blessing is the narrative sweep of the novel. Cast as a discovered document (there's a framing device about a world-weary translator who's been called to Egypt to read the memoir), this text often genuinely reads like something that might have been written by an ancient author. That gives it a convincing air. But it also undercuts one of the main pleasures we expect from a historical novel, a complete imaginative immersion in the times. We often find ourselves at one remove from Tiberius's experiences, not vividly present in the moment with him. When the author does switch to a more conventional storytelling style (conversations, descriptions, scenes structured to build to a dramatic end), it doesn't always work.
But on the plus side, I was never bored reading this book, and I found myself in sympathy with the gloomy world view (both of Tiberius and, I presume, of the novel's author), so that I looked forward to returning to the book each time I opened it. Despite displaying some of the typical awkwardness of a first novel, this is an ambitious book with a worthy theme, and if you are at all interested in the period, I recommend it.
