Geradus Mercator
Gerardus Mercator (5 March 1512 – 2 December 1594) was a 16th-century Southern Dutch cartographer, geographer and cosmographer. He was renowned for creating the 1569 world map based on a new projection which represented sailing courses of constant bearing (rhumb lines) as straight lines — an innovation that is still employed in nautical charts.
Mercator was one of the founders of the Netherlandish school of cartography and is widely considered the most notable figure of the school in its golden age (approximately 1570s–1670s). In his own day, he was a notable geographer, and maker of globes and scientific instruments. In addition, he had interests in theology, philosophy, history, mathematics and geomagnetism. He was also an accomplished engraver, calligrapher. Unlike other great scholars of the age he travelled little and his knowledge of geography came from his library of over one thousand books and maps, from his visitors and from his vast correspondence (in six languages) with other scholars, statesmen, travellers, merchants and seamen. Mercator's early maps were in large formats suitable for wall mounting but in the second half of his life, he produced over 100 new regional maps in a smaller format suitable for binding into his Atlas of 1595. This was the first appearance of the word Atlas in a geographical context but Mercator used it as a neologism for a treatise (Cosmologia) on the creation, history and description of the universe, not simply a collection of maps. He chose the word as a commemoration of the Titan Atlas, "King of Mauretania", whom he considered to be the first great geographer.
A large part of Mercator's income came from sales of his terrestrial and celestial globes. For sixty years they were considered the finest in the world, and were sold in such great numbers that there are many surviving examples. This was a substantial enterprise involving the manufacture of the spheres, printing the gores, building substantial stands, packing and distributing all over Europe. He was also renowned for his scientific instruments, particularly his astrolabes and astronomical rings used to study the geometry of astronomy and astrology.
Mercator wrote on geography, philosophy, chronology and theology. All of the wall maps were engraved with copious text on the region concerned. As an example the famous world map of 1569 is inscribed with over 5000 words in fifteen legends. The 1595 Atlas has about 120 pages of maps and illustrated title pages but a greater number of pages are devoted to his account of the creation of the universe and descriptions of all the countries portrayed. His table of chronology ran to some 400 pages fixing the dates (from the time of creation) of earthly dynasties, major political and military events, volcanic eruptions, earthquakes and eclipses. He also wrote on the gospels and the old testament.
Mercator was a devout Christian born into a Catholic family at a time when Martin Luther's Protestantism was gaining ground. He never declared himself as a Lutheran but he was clearly sympathetic and he was accused of heresy; after six months in prison he was released unscathed. This period of persecution is probably the major factor in his move from Catholic Leuven (Louvain) to a more tolerant Duisburg where he lived for the last thirty years of his life. Walter Ghim, Mercator's friend and first biographer, describes him as sober in his behaviour, yet cheerful and witty in company, and never more happy than in debate with other scholars. Above all he was pious and studious until his dying days."

The statue of Mercator
This statue is one of eight standing at each corner of the octagonal Palm House Building in Sefton Park.
"Sefton Park in Liverpool is arguably the best known and most loved by locals. Classified as a Grade One listed park by English Heritage, the magnificent 200-acre Park looks like a natural landscape rather than a man-made park. In spring the sight of millions of golden daffodils around the lake draws residents from across the city and carpets of bluebells give an impression of rural permanence.
The park features many distinctive curved paths and driveways and beech and other indigenous British trees abound. Amongst the park's many features are a boating lake, replica statues of Eros and Peter Pan and a café. The park is also home to the famous Palm House, a fabulous glass-panelled building that has been restored to its former glory."

The Palm House is a Historic England Grade II* Listed Building.
GV II* Palm House, built in 1896, designed by Mackenzie and Moncur. It is octagonal in plan. It has an iron frame on a granite base, with totally glazed openings. It appears as a sequence of three domical roofs, one above the other, including a clerestorey and lantern with a ball finial. The side elevations are of six bays with three round-arched lights and colonnettes to each bay, and ornamental cresting above. There are entrances to the north, south-east and west with barrel-vaulted porches that are enclosed at the sides and have ornamental gates, some with animals or birds. There are statues at each angle by Léon-Joseph Chavalliaud of famous gardeners, explorers and scientists. Flanking the north entrance are A le Notre and J Parkinson; to the east are Mercator and Captain Cook; to the south are Darwin and Linnaeus; and to the west are Henry the Navigator and Columbus."

The bronze statue is roughly 1 1/3 times life size. It shows Mercator holding one of his earth globes and there is an inscription on the plinth.
