Read the excerpt about Poseidon’s underwater home from The Myths and Legends of Ancient Greece and Rome by E. M. Berens.

This delightful abode was surrounded on all sides by wide fields, where there were whole groves of dark purple coralline, and tufts of beautiful scarlet-leaved plants, and sea-anemones of every tint. Here grew bright, pinky sea-weeds, mosses of all hues and shades, and tall grasses, which, growing upwards, formed emerald caves and grottoes such as the Nereides love, whilst fish of various kinds playfully darted in and out, in the full enjoyment of their native element. Nor was illumination wanting in this fairy-like region, which at night was lit up by the glow-worms of the deep.
