In 336BC, Alexander was not great. He was a wiry 20-year-old 'no one had thought much about' who found himself king of Macedon after his father Philip's assassination. He seemed uniquely unfit for the position. Darius III ruled more than 50 million people and was so confident of victory at Issus that he brought his family along to watch. Edmund Richardson, professor of classics at Durham, has written something that earns immediate comparison to the best popular history of the last decade — not just because of what it covers, but how it moves. The synthesis is real work: material from 12 languages, hieroglyphics, cuneiform, and computer simulations, filtered through a writer who clearly loves his subject without being precious about it. The question 'do we need another Alexander biography?' gets answered by the second chapter. The battle sequences are genuinely good. At Issus, the phalanx — a 16-man-deep war machine spiked with 19-foot spears — arrives with the specificity of an engineer's report. The siege of Tyre gets rendered through catapults, boring machines, tridents, and 'giant nests that snatched up men and dashed them against rocks.' At Gaugamela, Richardson gives you the operational detail that history books usually flatten: Darius might have won, had he known horses couldn't stomach the stench of elephants. But the book's real texture comes from everything between the battles. Alexander marching to Siwa, allowing the Egyptians to designate him son of Amun, then writing his mother a letter signed 'King Alexander, the son of Zeus Amun.' Her reply — 'My dearest boy, don't ever call yourself that again' — lands harder than any cavalry charge. At Susa, a drunk Alexander promises to pay off soldiers' debts and cover dowries: 'the most expensive hangover in history.' In Babylonia, the existential crisis accumulates: Is he king of Babylon or lord of two lands? Son of Philip or Amun? Actually a god? Richardson earns the digressions because the digressions are where the thinking lives. The chapter on Alexandria's library — a topic he's covered before in his 2021 book Alexandria: The Quest for the Lost City — lands as the book's intellectual centrepiece. The library produced designs for the first steam engine, an early calculation of the world's circumference, pneumatic singing mechanical birds, and the first universal editions of Homer. Richardson's claim that none of Alexander's ripples have shaped the world more than the library's legacy is the kind of argument that takes a full chapter to earn. He earns it. The comic register is consistent and earns trust. 'Persians were meant to be weak and uncivilised. Some of them even wore trousers.' Greek linguistic fixations get a bracket: 'Greek's fascination with the penis remains unrivalled.' And the survivors of the Trojan War who settled a new town called Pygela — 'which translates as Ass City' — appear with the timing of a good standup. This isn't comedy relief; it's Richardson's method of keeping the reader honest about what ancient history actually was. Alexander dies at 32, not heroically. His killer is salmonella typhi, likely from river water. 'The boy had become a king. The king had become a hero. The hero had become a living god. Now … the god was dying, slobbering and broken-hearted, in Babylon.' The pace holds through the final page — a feat for any biography of a life this long, this violent, this overstuffed with incident. Richardson shows that academic rigour and readability are not a trade-off. They are, in the right hands, the same thing.
