Try as I might, I cannot bring myself to give Fox's treatment of Alexander the lavish four and five stars that others have given. It's not that there aren't some qualities here worthy of praise, it's that there is far too much that detracts from the enjoyment.
This is the first biography of Alexander I have read, so I'm in no position to compare it to others out there. I can say, however, that Fox succeeds marvelously in bringing geography to life. Despite reading countless books about events in the Middle East, I never truly appreciated how formidable the climate there is until reading Fox. Fox presents a picture that is literally Alexander against the world - against deserts, mountains, heat, cold, snakes, and disease. For this alone, Fox's biography of Alexander is worth reading. I can think of no other historian who so skilfully matches events to geography.
Alas, there are some daunting downsides. While Fox's descriptions of geographic features are amazing, his maps are terrible. This is not entirely his fault; much of the blame lies with the black-and-white reprint. But even putting that aside, the maps given do not completely follow the text and are too few and too far spaced through the book to be much use. Far better to put several maps in one place at the beginning or end of the book for ease of reference. Too, Fox has a depressing tendency to talk in circles for pages on end, retelling the same event over and over and over with slight variations, then giving his own conclusions that sound an awful lot like the original version of the story presented pages before. The effect is to make the reader all the more sympathetic with Alexander's soldiers as they marched through the Makran desert; like them, the reader becomes opressed by the thought that the journey will never end, no matter how worthwhile the result will be.
