‘Apellabo martyrem; praedicavi satis.’
—St. Ambrose.
With what emotion must he who travels from the south first break upon the Campagna, and see presently the Appian Way. Here, on the outskirts of the City, is the heart of Rome. Not the centre of her grandeur and dominion, not the seat of justice and power, but the cradle of Christianity suffering and victorious.
‘Now—the single little turret that remains On the plains,
By the caper over-rooted, by the gourd Overscored . . . .
Here is ‘love among the ruins.’ But divine, not human, love. Along the line marked by the cypresses lie the catacombs, untouched by any pious transformation. These were the sleeping places of the martyrs. Who were they, and what have they done for Christianity?

No cause was ever so hopeless as that of Christianity on the morning after the Crucifixion. No religion has ever won a wider dominion in a shorter time.
