In the beginning there was only Chaos. Then out of the void appeared Night and Erebus, the unknowable place where death dwells. All else was empty, silent, endless, darkness. Then somehow Love (Eros) was born bringing a start of order. From Love came Light and Day. Once there was Light and Day, Gaea, the earth appeared.
Mercury, also known as Hermes to the Greeks, was the son of Zeus. Hermes is the god of shepherds, land travel, merchants, weights and measures, oratory, literature, athletics and thieves, and known for his cunning and shrewdness. According to legend, Hermes was born in a cave on Mount Cyllene in Arcadia. Zeus had impregnated Maia at the dead of night while all other gods slept. When dawn broke amazingly he was born. Maia wrapped him in swaddling bands, then resting herself, fell fast asleep. Hermes, however, squirmed free and ran off to Thessaly. This is where Apollo, his brother, grazed his cattle. Hermes stole a number of the herd and drove them back to Greece. He hid them in a small grotto near to the city of Pylos and covered their tracks. Before returning to the cave he caught a tortoise, killed it and removed its entrails. Using the intestines from a cow stolen from Apollo and the hollow tortoise shell, he made the first lyre. When he reached the cave he wrapped himself back into the swaddling bands. When Apollo realized he had been robbed he protested to Maia that it had been Hermes who had taken his cattle. Maia looked to Hermes and said it could not be, as he is still wrapped in swaddling bands. Zeus the all powerful intervened saying he had been watching and Hermes should return the cattle to Apollo. As the argument went on, Hermes began to play his lyre. The sweet music enchanted Apollo, and he offered Hermes to keep the cattle in exchange for the lyre. Apollo later became the grand master of the instrument, and it also became one of his symbols. Later while Hermes watched over his herd he invented the pipes known as a syrinx (pan-pipes), which he made from reeds. Hermes was also credited with inventing the flute. Apollo, also desired this instrument, so Hermes bartered with Apollo and received his golden wand which Hermes later used as his heralds staff.
