What happened?

It took Gibbon six volumes to describe the decline and fall of the Roman Empire, so I shan’t embark on that. But thinking about this almost incredible episode does tell one something about the nature of civilisation.

It shows that however complex and solid it seems, it is actually quite fragile. It can be destroyed.

What are its enemies?
Well, first of all fear — fear of war, fear of invasion, fear of plague and famine, that make it simply not worthwhile constructing things, or planting trees or even planning next year’s crops. And fear of the supernatural, which means that you daren’t question anything or change anything.

The late antique world was full of meaningless rituals, mystery religions, that destroyed self-confidence. And then exhaustion, the feeling of hopelessness which can overtake people even with a high degree of material prosperity. There is a poem by the modern Greek poet, Cavafy, in which he imagines the people of an antique town like Alexandria waiting every day for the barbarians to come and sack the city. Finally the barbarians move off somewhere else and the city is saved; but the people are disappointed — it would have been better than nothing.

Of course, civilisation requires a modicum of material prosperity — What civilization needs: confidence in the society in which one lives, belief in its philosophy, belief in its laws, and confidence in one’s own mental powers. The way in which the stones of the Pont du Gard are laid is not only a triumph of technical skill, but shows a vigorous belief in law and discipline.

Vigour, energy, vitality: all the civilisations — or civilising epochs — have had a weight of energy behind them.

People sometimes think that civilisation consists in fine sensibilities and good conversations and all that. These can be among the agreeable results of civilisation, but they are not what make a civilisation, and a society can have these amenities and yet be dead and rigid.

Energy is eternal delight; and from the earliest times human beings have tried to imprison it in some durable hieroglyphic. It is perhaps the first of all the subjects of art.

There is no doubt that Goya thought that one of the drugs chiefly responsible for the sleep of reason was the Church, and he had the lowest possible opinion of ecclesiastical institutions. However, this did not prevent him from painting religious pictures, completely sincerely because, like all Latin people, however little he believed in Christianity, he felt himself to be within the structure of the Catholic Church. One of his finest works was the decoration of a church near Madrid called S. Antonio de la Florida. He used the kind of device that would have appealed to Tiepolo. He painted a balcony round the drum of a cupola, and behind it he put a crowd of loiterers who are supposed to be watching the saint raise a man from the dead. Very few of them are interested in this unusual event. They are interested in each other or themselves, and show very well the curious tension between the individual and the collective, which is the essence of a crowd.
