A technological development that permitted sailors to estimate how far east and west they are is the invention of portable, reliable timepieces.  There is a wonderful non-fiction book about this called "Longitude" by Dave Sobel.\n\nhttp://www.amazon.com/Longitude-Genius-Greatest-Scientific-Problem/dp/0140258795/\n\nThe concept of time based navigation had been around for quite a while, but it took a long concerted effort to develop the tools necessary. John Harrison developed his first mechanical chronometer over seven years and tested it at sea for the first time in 1738.\n\nAs was said above, North-South navigation has been around since prehistory.

There's still disagreement about just where Columbus first saw the new world and set foot upon its shores.  No one knows for sure.\n\nHere are some sites that may be helpful to you.  Best of luck.

Where did you see it referenced?  Are you certain of the spelling?  I have access to a scientific database but the word "teoglico" was not found.

Aha!\n\nPerhaps it would be best to clue you into a direct exploration currently in progress:\n\nIn short, this is directly copied from the BBC :)  The exploration continues, and more evidance is being found, so good reading:\n\nAmerican researchers claim to have found convincing evidence that locates the site of the lost kingdom of Atlantis off the coast of Cyprus. \nThe team spent six days scanning the Mediterranean sea bed between Cyprus and Syria using sonar technology. \n\nThey believe they found evidence of massive, manmade structures beneath the ocean floor, including two straight, 2-km (1.25 mile) long walls on a hill. \n\nThey say their discoveries match accounts of the city written by Plato. \n\n\n'Greatest coincidence' \n\nTeam leader Robert Sarmast said the walls appear to be sited on a flat-topped hill where the temples of Atlantis once stood. \n\n \nMyth or reality? It is said to be a place of beauty and wealth \nHe intends to use the sonar data to make a three-dimensional computer image of the site, 1.5km below sea level, before returning for further research. \n\n\n"The hill, as a whole, basically looks like a walled, hillside territory and this hillside territory matches Plato's description of the Acropolis hill with perfect precision," he said. \n\n"Even the dimensions are exactly perfect, so if all these things are coincidental, I mean, we have the world's greatest coincidence going on." \n\nHowever, Mr Sarmast and his team are not alone in believing they have found the lost city of Atlantis. \n\n \nSonar technology was used to survey the sea bed off Cyprus \nOther researchers have placed it off the coast of Spain, Cuba and the south west of England, as well as under the South China Sea. \n\nThe story of Atlantis, a fabled utopia destroyed in ancient times, has captured the imagination of scholars ever since it was first described by the philosopher Plato. \n\nWriting more than 2,000 years ago, he depicted a land of fabulous wealth, advanced civilisation and natural beauty.

Funny question!!! I'd say the Phoenicians were the ones who discovered us in the sense Columbus discovered America. The sailed the Mediterranean, arrived in the South of Spain 3000 years ago and founded the town of Cadiz, which still exists. Actually, it is the oldest Western town!!
