It was higher than all its neighbours and free from any volcanic activity. They took all their equipment up loaded on mules, except for the Pattinson telescope which was much too bulky. They stayed there a month making astronomical, meteorological and

found both much better than at Edinburgh. He also made the first positive detection of heat coming from the Moon

were annoyed by frequent dust incursions which frequently blotted out the horizon. Even when the dust was at its worst, the transparency at
the zenith was better than at Edinburgh.
The dust was evidently confined to individual layers, so he decided to move to Alta Vista at 10700 ft (3,261.4 m), on the eastern slope of Teide, the highest point that mules could reach. He was determined to use the larger Pattinson telescope and returned to Orotava to fetch it. As the three
boxes were too heavy, they were opened and the contents distributed
among several smaller boxes which were loaded on to seven strong
horses. The telescope was soon mounted and in action. The Airy Disc

Pyramidological researches

Smyth corresponded with pyramid theorist John Taylor
John Taylor (1781-1864)
John Taylor was a publisher, essayist, and writer born in East Retford, Nottinghamshire, the son of James Taylor and Sarah Drury. Although in pyramidical circles, he may be remembered for his contributions to Pyramidology and his use of that subject in the fight against adopting the metric system...

 and was heavily influenced by him. Taylor theorized in his 1859 book The Great Pyramid: Why Was It Built? & Who Built It? that the Great Pyramid was planned and the building supervised by the biblical Noah
Noah
Noah was, according to the Hebrew Bible, the tenth and last of the antediluvian Patriarchs. The biblical story of Noah is contained in chapters 6–9 of the book of Genesis, where he saves his family and representatives of all animals from the flood by constructing an ark...

. Refused a grant by the Royal Society, Smyth went on an expedition to Egypt in order to accurately measure every surface, dimension, and aspect of the Great Pyramid. He brought along equipment to measure the dimensions of the stones, the precise angle of sections such as the descending passage, and a specially designed camera
Camera
A camera is a device that records and stores images. These images may be still photographs or moving images such as videos or movies. The term camera comes from the camera obscura , an early mechanism for projecting images...

 to photograph both the interior and exterior of the pyramid. He also used other instruments to make astronomical calculations and determine the pyramid's accurate latitude and longitude.
Smyth subsequently published his book Our Inheritance in the Great Pyramid in 1864 (which he expanded over the years and is also titled The Great Pyramid: Its Secrets and Mysteries Revealed). Smyth claimed that the measurements he obtained from the Great Pyramid of Giza indicated a unit of length, the pyramid inch
Pyramid inch

.

Smyth claimed, and presumably believed, that the pyramid inch was a God-given measure handed down through the centuries from the time of Shem (Noah's Son), and that the architects of the pyramid could only have been directed by the hand of God. To support this Smyth said that, in measuring the pyramid, he found the number of inches in the perimeter of the base equalled one thousand times the number of days in a year, and found a numeric relationship between the height of the pyramid in inches to the distance from Earth to the Sun, measured in statute miles. He also advanced the theory that the Great Pyramid was a repository of prophecies

Smyth, despite his bad reputation in Egyptological circles today, performed much valuable work at Giza. He made the most accurate measurements of the Great Pyramid that any explorer had made up to that time, and he photographed the interior passages, using a magnesium

 light, for the first time. Smyth's work resulted in many drawings and calculations, which were soon incorporated into his books Our Inheritance in the Great Pyramid, the three-volume Life and Work at the Great Pyramid (1867), and On the Antiquity of Intellectual Man (1868). For his works he was awarded a gold metal by the Royal Society of Edinburgh, but in 1874, the Royal Society rejected his paper on the design of Khufu's pyramid, as they had Taylor's. The rejection of his ideas helped contribute to his resignation from his post as Royal Astronomer in 1888.

Influence of Smyth's pyramid theories

Smyth's theories on pyramid prophecy were then integrated into the works and prophecies of Charles Taze Russell

, first 1882 then many dates between 1892 and 1911, were failed predictions.

The theories of Taylor and Smyth gained many eminent supporters and detractors in the field of Egyptology during the late 1800s, but by the end of the 19th century it had lost most of its mainstream scientific support. The greatest blow to the theory was dealt by the great Egyptogist William Matthew Flinders Petrie

William Matthew Flinders Petrie FRS , commonly known as Flinders Petrie, was an English Egyptologist and a pioneer of systematic methodology in archaeology and preservation of artifacts...

, who had initially been a supporter. When Petrie went to Egypt in 1880 to perform new measurements, he found that the pyramid was several feet smaller than previously believed. This so undermined the theory that Petrie rejected it, writing "there is no authentic example, that will bear examination, of the use or existence of any such measure as a 'Pyramid inch,' or of a cubit of 25.025 British inches."

Marriage, family, and death
