Man came across coral in ancient times, since then he has always been fascinated by it, maybe because of its color, as red as blood and a symbol of life and a form protection against death. Its mythical origins are narrated in Ovid’s Metamorphoses. He tells that Perseus, after cutting off Medusa’s head, puts it on some water twigs, which once absorbed the red blood, got hard. In fact, once in the air, the coral hardens, although before it was alive and sinuous.
Its rarity and its ambiguous nature have contributed to increase its value. What is coral indeed? A flower blossomed from the water, a precious mineral or something alive? Over the centuries, coral has been linked to each natural kingdom: animal, mineral and plant. Yet,scientists, men of culture and naturalists have been unable to determine its soul so far.
Coral is a hard substance that forms in the sea from the skeletons of some octocorals anthozoan coelenterates, belonging to the order of gorgonari. Coral grows in relatively hot and non-polluted waters, at average depth, even if these are not the only natural conditions for its life. This very particular sea animal has inhabited seabeds and oceans since life had not spreed on the mainland yet. Typically coral lives in colonies which look like tree-shaped limestone .The particular “aspect” in which it grows has reinforced the belief of its link with life and its magical value for many peoples. There are different varieties of coral, some coming from from the Mediterranean, as well as the ones coming from oriental seas.
