Phosphorescence and Fireflies

The phosphorescence was particularly good that night. By plunging your hand into the water and dragging it along you could draw a wide golden-green ribbon of cold fire across the sea, and when you dived as you hit the surface it seemed as though you had plunged into a frosty furnace of glinting light. When we were tired we waded out of the sea, the water running off our bodies so that we seemed to be on fire, and lay on the sand to eat. Then, as the wine was opened at the end of the meal, as if by arrangement, a few fireflies appeared in the olives behind us – a sort of overture to the show.

First of all there were just two or three green specks, sliding smoothly through the trees, winking regularly. But gradually more and more appeared, until parts of the olive grove were lit with a weird green glow. Never had we seen so many fireflies congregated in one spot; they flicked through the trees in swarms, they crawled on the grass, the bushes and the olive trunks, they drifted in swarms over our heads and landed on the rugs like green embers. Glittering streams of them flew out over the bay, swirling over the water, and then, right on cue, the porpoises appeared, swimming in line into the bay, rocking rhythmically through the water, their backs as if painted with phosphorus. In the centre of the bay they swam round, diving and rolling, occasionally leaping high in the air and falling back into a conflagration of light. With the fireflies above and the illuminated porpoises below it was a fantastic sight. We could even see the luminous trails beneath the surface where the porpoises swam in fiery patterns across the sandy bottom, and when they leaped high in the air the drops of emerald glowing water flicked from them, and you could not tell if it was phosphorescence or fireflies you were looking at. For an hour or so we watched this pageant, and then slowly the fireflies drifted back inland and farther down the coast. Then the porpoises lined up and sped out to sea, leaving a flaming path behind them that flickered and glowed, and then died slowly, like a glowing branch laid across the bay.
