“We might place Ransonnet-Villez in the naturalist tradition, following Philip Henry Gosse, whose The Aquarium of 1854 was a high-water mark in interest in observing marine ecology at close hand. But Ransonnet-Villez deserves special mention for his dedication to conveying the sight and feel of the ocean, his literal immersion in his subject. As he explained of his diving-bell drawing excursions, “one's normal sense of distance and size is completely lost. You soon realize that in the depths of the ocean you need not only learn how to move, but how to see and hear as well.”
