Santiago Sevilla is a historian, playwright, novelist and poet. In English he has writen; "King Peter the Cruel"; "Dracula and the Bloody Mary", and the novel "Goodbye Colombia". Per Internet, his work, in Spanish, English and German, has been published in Liceus.com. As a historian, he has discovered the author of the famous tale of chivalry "Amadis de Gaula". He is Enrique de Castilla, brother to the Queen of England, Eleanor of Castile, wife of Eduard I Longshanks. Santiago Sevilla has translated fifty sonnets of Shakespeare into Spanish sonnets. Santiago Sevilla defends the theory that Stonehenge was not only a construction to measure time by weeks and months, but also a ditched enclosure to herd wild game: Aurochs, deer and boar, by Neolithic hunters. He believes that the megalits emplaced in the Sarsen Circle of Stonehenge are a tactical fortification for the hunters, to fight off attacking enemies, other hunters from the Continent.At the same time, the 56 megaliths around the circle of Stonehenge account for 56 weeks of 6.5 days in a year of 364 days. In Spanish Santiago Sevilla has published, both in Liceus and in Scribd through Internet the following tragic plays: Alejandro Magno Julio César y Cleopatra Juliano el Apóstata El Rey Don Pedro el Cruel published at Biblioteca Virtual Miguel de Cervantes El Gran Condestable Don Álvaro de Luna Juana la Beltraneja Juana la Loca Cesare Borgia Duque Valentino Tenochtitlan o La Conquista de México Cajamarca o La Leyenda Negra

He has also published in Liceus and Scribd in Internet the comedies: Drácula y La Vampiresa La Democracia Feliz La Bella y la Bestia

A number of short stories and his poetry have also been published in Liceus.com, and in Scribd by Internet

Santiago Sevilla has translated King Richard II by William Shakespeare, in verse, from English to Spanish. This famous poetic tragedy appears in Liceus.com as well as in Scribd. A contribution to clearing Stonehenge's mystery is the study made by Santiago Sevilla regarding Stonehenge numbers.He states: "Deciphering the numbers of Stonehenge helps to understand its significance. To begin with, we must pay attention to the Aubrey Holes which are 56 in number. Little heed has been given to this count, but it entrails a revelation: If we multiply 56 by 6.5, we find that the resulting number is 364, equivalent to days in a year, according to certain circumstance. Or, if we divide 364 days of the year by 56, we find that the resulting number is 6.5, which corresponds to the number of days of the week, according to the way the week was defined by the Assyrians at that same time, five thousand years ago. The Assyrian week had six days. One can conclude, that Aubrey Holes account for each week of the year, 56 in total. Stonhenge is divided by a straight line, which points to the sunrise at the summer solstice, the day of the year when the sun reaches the most northerly point on the horizon. This day is the 21st. of June. The same line points to the opposite direction towards the winter solstice sunset.This day is the 21st. of December. If we count the days from the 21st. of December to the 20th. of June, we reckon 181 days. When we count the number of days between the 21st. of June to the 20th. of December, we reckon 183 days. If we add both periods, we establish the number of 364 days. So the line divides the year into two halves,part of Summer, Autumn and part of Winter, on one hand; part of Winter, Spring and part of Summer on the other. The year represents again 364 days. Both, by account of 56 weeks of 6.5 days, or by account of days between the sunrise of the solstice of Summer and the winter solstice sunset, plus the number of days back to the day of the sunrise at the summers solstice, we find the number 364 days, equivalent to the year. This coincidence shows that the builders of Stonehenge wanted the circle to represent a calendar to measure time by weeks and days based on the sunrise of the summer solstice. That is the role of the famous 56 pits just inside the bank known after the discoverer, as the Aubrey Holes. But there is more to discover based on the numbers of Stonehenge. Its diameter, from the Slaughter Stone to the opposite side at the top of the embankment along the dividing line which connects both solstices of summer to winter, is equal to one hundred meters. The perimeter of Stonehenge is so, by definition, equal to Pi (3,1416) multiplied by 100 meter, equal to 314,16 meters. The distance between the Aubrey Holes would be equal to 314,16 divided by 56, which ammounts to 5.61 meters. It actually is a bit less because the holes are dug inside the circle, and not on the perimeter. But they have been dug along a radius towards the middle point of the circular embankment. It appears that the designers of Stonehenge worked under the assumption that the year at 364 days, or 56 weeks of 6.5 days, was almost equal to the circle of 360 degrees. So Stonehenge was a reflection of the firmament, and a calendar, superposed. Today science has defined a year as equal to 365.242199 days. The month, or Lunation, is today defined by science as equal to 29.53059 days. Stonehenge has Lunation defined by thirty days, which would make a year of 360 days, equivalent to degrees in a circle. The difference with a full year is given by the 5 Trillithons, which round up to 365 days. So the lunar count is adjusted to the count based on the appearance of the sun. In Stonehenge, the Y holes are numbered thirty, the Z holes are also numbered 30. The Sarsen circle is made by thirty grounded mega stones. If we add theses numbers to 90 days, we establish the length of each season, Summer, Autumn, Winter and Spring, each three months. Nevertheless, the numbers of Stonehenge appear to be ruled mostly by the sun. At any rate, the conclusion of the study of the numbers of Stonehenge induces to the assertion that the hunters who lived around Stonehenge knew about the definition of the circle, knew the meter, used the natural number 3.1416 or Pi, established the relation between the numbers of days in a year and the degrees of a circle, and were almost as accurate as modern mathematicians or astronomers, regarding the days of the year, the number of weeks in a year, the number of days in a week, all consistent with eachother. Months gave them to struggle, but they bridged the inconsistency by introducing the five Trillithons, so the year was an approximation between 364 and 365 days by both counts. It is conceivable, that, at the times of design and construction of Stonehenge, this ability had been acquired by its builders, from some contact with Assyria, and Egypt, which had rather advanced astronomy and mathematics. Human intelligence was as good as today, although human science and technology had not yet stored much knowledge in England by those days. Numbers were, notwithstanding, a given fact of life. Fortunately, the decimal system had been conveyed to us by our own hands through their ten fingers." Santiago Sevilla based this study on information from the Encyclopaedia Britannica.
