Question:
James Hudson Taylor (Chinese: Dai De Sheng ; 21 May 1832 - 3 June 1905) was a British Protestant Christian missionary to China and founder of the China Inland Mission (CIM, now OMF International). Taylor spent 51 years in China. The society that he began was responsible for bringing over 800 missionaries to the country who began 125 schools and directly resulted in 18,000 Christian conversions, as well as the establishment of more than 300 stations of work with more than 500 local helpers in all eighteen provinces.
Due to health issues, Taylor remained in Switzerland, semi-retired with his wife. In 1900, Dixon Edward Hoste was appointed the Acting General Director of the CIM, and in 1902, Taylor formally resigned. His wife, Jennie, died of cancer in 1904 in Les Chevalleyres, Switzerland, and in 1905, Taylor returned to China for the eleventh and final time. There he visited Yangzhou and Zhenjiang and other cities, before dying suddenly while reading at home in Changsha. He was buried next to his first wife, Maria, in Zhenjiang, in the small English Cemetery near the Yangtze River. The small cemetery was built over with industrial buildings in the 1960s and the grave markers were destroyed. However, the marker for Hudson Taylor was stored away in a local museum for years. His great-grandson, James Hudson Taylor III, found the marker and was able to help a local Chinese church re-erect it within their building in 1999. His re-erected tombstone reads: In 2013 the land for the cemetery was re-developed and the demolition of the old industrial buildings revealed that the Taylors' tombs were still intact. On 28 August the graves were excavated with the surrounding soil and moved to a local church where they will be reburied in a memorial garden. Picture of gravestone and stele at Xuande Church in Zhenjiang. Gravestone is underground in a pit where the church is awaiting construction of a proper memorial hall - timeline for completion of memorial hall is postponed according to church officials. [1] Dedication marker is outside under a tarp covered up unless visitors know it is there. [2] Currently in possession of Xuan De Tang (Zhen Jiang Shi ) as of July 2016.

Question:
Claudius Ptolemy (; Greek: Klaudios Ptolemaios, Klaudios Ptolemaios [klawdios ptoleme:os]; Latin: Claudius Ptolemaeus; c. AD 100 - c. 170) was a Greco-Roman mathematician, astronomer, geographer, astrologer, and poet of a single epigram in the Greek Anthology. He lived in the city of Alexandria in the Roman province of Egypt, wrote in Koine Greek, and held Roman citizenship. The 14th-century astronomer Theodore Meliteniotes gave his birthplace as the prominent Greek city Ptolemais Hermiou
Ptolemy's Almagest is the only surviving comprehensive ancient treatise on astronomy. Babylonian astronomers had developed arithmetical techniques for calculating astronomical phenomena; Greek astronomers such as Hipparchus had produced geometric models for calculating celestial motions. Ptolemy, however, claimed to have derived his geometrical models from selected astronomical observations by his predecessors spanning more than 800 years, though astronomers have for centuries suspected that his models' parameters were adopted independently of observations. Ptolemy presented his astronomical models in convenient tables, which could be used to compute the future or past position of the planets. The Almagest also contains a star catalogue, which is a version of a catalogue created by Hipparchus. Its list of forty-eight constellations is ancestral to the modern system of constellations, but unlike the modern system they did not cover the whole sky (only the sky Hipparchus could see). Across Europe, the Middle East and North Africa in the Medieval period, it was the authoritative text on astronomy, with its author becoming an almost mythical figure, called Ptolemy, King of Alexandria. The Almagest was preserved, like most of extant Classical Greek science, in Arabic manuscripts (hence its familiar name). Because of its reputation, it was widely sought and was translated twice into Latin in the 12th century, once in Sicily and again in Spain. Ptolemy's model, like those of his predecessors, was geocentric and was almost universally accepted until the appearance of simpler heliocentric models during the scientific revolution. His Planetary Hypotheses went beyond the mathematical model of the Almagest to present a physical realization of the universe as a set of nested spheres, in which he used the epicycles of his planetary model to compute the dimensions of the universe. He estimated the Sun was at an average distance of 1,210 Earth radii, while the radius of the sphere of the fixed stars was 20,000 times the radius of the Earth. Ptolemy presented a useful tool for astronomical calculations in his Handy Tables, which tabulated all the data needed to compute the positions of the Sun, Moon and planets, the rising and setting of the stars, and eclipses of the Sun and Moon. Ptolemy's Handy Tables provided the model for later astronomical tables or zijes. In the Phaseis (Risings of the Fixed Stars), Ptolemy gave a parapegma, a star calendar or almanac, based on the hands and disappearances of stars over the course of the solar year.
