" At the end of the first century of Christian rule, the Colosseum still dominated Rome and the Parthenon towered above Athens. Yet when writers of this period discuss architecture, these aren’t the buildings that impress them. Instead, their admiration is drawn by another structure in Egypt. This building was so fabulous that writers in the ancient world struggled to find ways to convey its beauty. ‘Its splendour is such that mere words can only do it an injustice,’ wrote the historian Ammianus Marcellinus. It was, another writer thought, ‘one of the most unique and uncommon sights in the world. For nowhere else on earth can one find such a building.’ Its great halls, its columns, its astonishing statues and its art all made it, outside Rome, ‘the most magnificent building in the whole world’. Everyone had heard of it. No one has heard of it now. While tourists still toil up to the Parthenon, or look in awe at the Colosseum, outside academia few people know of the temple of Serapis. That is because in AD 392 a bishop, supported by a band of fanatical Christians, reduced it to rubble. "
