Marcus Aurelius felt as deeply as our own Shakespeare seems to have felt the unsubstantiality, the fleeting evanescence of all earthly things: he would have delighted in the sentiment that, "We are such stuff As dreams are made on, and our little life Is rounded by a sleep.

" This image of misery was perhaps originally suggested to some poet by the conduct of his patron, by the daily contemplation of splendour which he never must partake, by fruitless attempts to catch at interdicted happiness, and by the sudden evanescence of his reward, when he thought his labours almost at an end.

Of the great principles of truth which the first speculatists discovered, the simplicity is embarrassed by ambitious additions, or the evidence obscured by inaccurate argumentation; and as they descend from one succession of writers to another, like light transmitted from room to room, they lose their strength and splendour, and fade at last in total evanescence.

It is impossible to witness such a beautiful phenomenon without a sense of awe, and yet this sentiment is not inspired by its brilliancy but rather by its delicacy in light and colour, its transparency, and above all by its tremulous evanescence of form.
