The negative effect of the Road, the effect of its breakdown, especially at the bridges and in the causeways over marshy land, is equally indisputable in human relations. We have the typical case of Sussex remaining heathen for one hundred years after the conversion of its neighbours, because the main road from the north with its causeway everywhere crossing the clay and piercing the scrub of the weald fell into decay, and because the bridge at Alfoldean broke down. It is most significant that the great battle of Ockley was fought north of this break in communications. The Danes, marching from London against the English army, could get down as far south as this, and the English army coming up from Hampshire could intercept them as far south as this, but all the Danish attack on Sussex, such as it was (and it was very slight), came from the sea. Another very conspicuous example of the breakdown of the Road and of the political effect thereof is the chaos you get in the Balkan peninsula after the decay of the great Roman trunk roads. If the Greek Church is to-day separate from the Latin Church to the west it is due not only to the obstacle of the Pinsk Marshes in the north, but to the gradual decline in the south of the main artery between Durazzo and Constantinople. For centuries old and new Rome communicated by the great trunk road down to Brundusium and then across the narrow sea to Dyracchium and Byzantium. When that traffic began to be interrupted the contrast between the east and the west was founded and increased.
