I hope that this theoretical “essay” will be better received than a certain practical essay that I undertook, soon after my arrival in Paris, in the cathedral of Notre Dame.

Notre Dame! The great cathedral of which France is justly proud was naturally the objective of one of my earliest artistic pilgrimages, I may say of the very earliest. The tall columns, whose shafts, composed of little assembled columns, rise clear to the vaults; the admirable proportions of the nave; the choir, the seats of old carved oak, and the railings of wrought iron—this harmonious and magnificent pile impressed me deeply. But what enchanted me more than anything else was the marvellous glass of the lateral rose windows, and even more, perhaps, the rays of sunlight that vibrated in the church, in various directions, intensely coloured, as a result of having passed through these sumptuous windows.

I quite forgot where I was. I took my handkerchief from my pocket, a white handkerchief, and I waved it in the beams of coloured light, just as in the evening I waved my silken materials in the rays of my reflectors.

Suddenly a tall imposing man, adorned with a heavy silver chain, which swung from an impressive neck, advanced ceremoniously toward me, seized me by the arm and led me toward the entrance, directing a conversation at me which I appreciated as lacking in friendliness although I did not understand a word. To be brief he dropped me on to the pavement. There he looked at me with so severe an expression that I understood his intention was never to let me enter the church again under any pretext.

My mother was as frightened as I was.

Just then a gentleman came along, who, seeing us completely taken aback, asked us what had happened. I pointed to the man with the chain, who was still wrathfully surveying us.

“Ask him about it,” I said.

The gentleman translated the beadle’s language to me.

“Tell that woman to go away; she is crazy.”

Such was my first visit to Notre Dame and the vexatious experience that my love of colour and light caused.
