While it is really amazing that we have this large segment of a type of travel diary -- or, perhaps something of a journal intended for her "sisters" to whom she refers often -- kept by a woman named Egeria as she traveled through much of the Holy Land as well as parts of Egypt, modern-day Turkey, and present-day Iraq sometime in the late 4th century, I have given it only 3 stars for this reasons:
1) Disappointingly (at least for me), in her travels she says almost nothing about what she sees that we, some 1,700 years later, might wish that she had recorded: in the way of "sights" and "sounds" that would unravel the years for us in an almost "you are there" way;
2) What's more, her comments are almost exclusively about the many churches and "holy places" she visits, including very detailed notes about the liturgies of the day. (Some of this would have been interesting, but it becomes more than a tad too much with seemingly endless repetition.)
Scholars speculate that she was either a female religious of some sort (not necessarily "professed," as in a "member of a particular order of nuns" but, perhaps, a devout female layperson) or a woman of some status as such a trip would have been simply out of the question for most people at that time.
One of the things I noted that seemed not unlike our own times is that I think there were a lot of -- for want of a better term -- hucksters in her day who conveniently provided pious travelers of the time with an abundance of "holy sites" and even "relics of the past," such as the actual tomb of Job and pieces of the cross upon which Jesus had been crucified.
The great era of "holy" pilgrimages was still some centuries in the future, and so it is fascinating to learn something of these days when the Roman Empire in the West still existed, albeit in weakened condition. (On several occasions she mentioned being accompanied by Roman soldiers on segments of the journey that were apparently frequented by those who preyed upon travelers.
For persons interested either in this period of time or in pious expressions of early Christian sentiment I believe that this book would be of some interest, my caveats notwithstanding. (The extensive introductory notes about Egeria, her time, and the state of both holy sites and religious practices are worth the modest price of the book alone.)
