1 Icelandic Commonwealth absent Confident Expert 930 CE 1100 CE
absent/present/unknown Durrenberger notes the presence of legal and grammatical literature: ’According to most authors writing was introduced to Iceland when the country was Christianized in the year 1000. In the two centuries that followed, writing was used for many purposes: religious works, a grammar, a law book and a short history. Most of the family sagas were written in the thirteenth century. The saga with which I am concerned, Eyrbyggja saga (ÍF 4), is commonly believed to have been written between 1230-1250 (Schach & Hollander 1959:xx). I shall deal only with a part of this saga, which I have called the Þórgunna story (ÍF 4, ch. 49-55). I consider the Þórgunna story a myth. Anthropologists believe that myths contain hidden messages in symbolic forms. According to Malinowski (1926) myths are social charters. Lévi-Strauss (1963) argues that myths have a binary structure and that their oppositions explore contradictions in social and other relations.’ [1] The Grágás legal code is one example: ’It is impossible to say how much of this book is represented in Grágás. Grágás has been preserved in two manuscripts which date to about 1260 and 1280. It is not possible to assign dates to individual provisions within it. The provenance of the manuscripts is unknown and neither is an official compilation (Miller 1990: 42).’ [2] Some sources include passages of a scientific nature: ’In “Alfræði íslenzk” there are some texts that may be called of a scientific nature. Some texts from this source are definitely from the Commonwealth period.’ [3]

5 Russian Empire, Romanov Dynasty I Transitional (Absent -> Present) Confident Expert 1615 CE 1700 CE
Early 17th Century (1615-1700): In the early part of this period, scientific literature in Russia was quite limited. The country was largely isolated from the scientific advancements occurring in Western Europe. Most scholarly works were religious or philosophical in nature, and there was minimal engagement with the scientific ideas that were developing in Western Europe during the Renaissance and early Enlightenment.

Reign of Peter the Great (1682-1725): A significant change occurred during the reign of Peter the Great. Peter’s extensive efforts to modernize and Westernize Russia had a profound impact on the sciences. He founded the Russian Academy of Sciences in St. Petersburg in 1724, marking the beginning of a systematic approach to scientific research and literature in Russia. This period saw an influx of European scientists and the introduction of contemporary scientific ideas from Western Europe. [1]

For example works by:

Mikhail Lomonosov (1711–1765): Lomonosov was a polymath, scientist, and writer who made significant contributions to literature, education, and science, particularly in chemistry and physics. He wrote numerous scientific works and was instrumental in the establishment of Moscow State University. [2]



Vasily Nikitich Tatishchev (1686–1750): Tatishchev was a prominent Russian statesman and historian who is often considered the father of Russian historiography. He conducted geographical and ethnographic studies and wrote a comprehensive history of Russia. [3]

6 Early Modern Sierra Leone absent Inferred 1650 CE 1832 CE
The following quote implies that indigenous writing emerged in the region in the 19th century. "The first documented autochthonous, Mande script to appear in West Africa was the one created by Duala Bukere from Grand Cape Mount County in Liberia who created a Vai syllabary in 1833, which has been standardized to 212 characters (Dalby, 1967: 14-18). [...] Appearing first in the region, the Vai syllabary became the prototype for other writing systems that were created in the inter-wars among indigenous peoples in Sierra Leone and Liberia. Speakers of southern Mande languages such as the Mende (1921) and the Kpelle (1935), and speakers of the Kru languages such as the Bassa (1920-25) have based their writing systems on the syllabary (Dalby, 1967: 2-4)."

10 Spanish Empire II present Confident Expert 1716 CE 1814 CE
Science; mathematics; economics. “Charles III, who has been described (perhaps unwisely) as an “enlightened despot” on the model of Frederick the Great and Joseph II, also supported the formation of local societies known as Los Amigos del País to discuss schemes for improving their regional economies. By the end of the reign there were 54 of them in the peninsula, although no more than half ever became truly active. In some regions the societies’ commitment to change aroused the opposition of the church and of local elites who saw nothing wrong with the status quo. Periodicals sanctioned by the crown to further scientific and economic interests rarely found more than a few hundred subscribers.”(Maltby 2009: 179-180) Maltby, William S. 2009. The Rise and Fall of the Spanish Empire. New York: Palgrave Macmillan. https://www.zotero.org/groups/seshat_databank/items/itemKey/SUSVXWVH “Court culture included an affinity for the mathematical and scientific interests of the Jesuits as well as the early stirrings of the Spanish Enlightenment, most notably in the writings of the Benedictine monk Benito Feyjóo. Lamenting that Spain had fallen behind its European neighbors in intellectual pursuits, Feyjóo argued tirelessly for a new spirit of inquiry, particularly in the sciences. Although his writings met with strong criticism from traditionalists, Feyjóo enjoyed the steadfast support of the king.”(Philips and Philips 2010: 185) Philips, William D. and Carla Rahn Philips. 2010.

16 Austria - Habsburg Dynasty II present Confident 1867 CE 1918 CE
“The eighteenth century saw a veritable explosion of published works of literature, science, history, religion, and philosophy in the territories ruled by the Habsburgs.” [1] “In 1883 under the patronage of Crown Prince Rudolf, the government of Austria-Hungary initiated a vast proj ect to make visible the diversity and dimensions of empire. Th e goal was to collect studies of the empire’s highly diverse geology, flora, fauna, and populations in a set of illustrated volumes to be made available for public subscription: the so- called Kronprinzenwerk.” [2] “In 1847 the Academy of Sciences was organized, with a philosophic-historical section and a second one dedicated to research in the natural sciences—belatedly in comparison with similar institutions in other countries.” [3]

“The influence of Islamic medicine on China during the period was also substantial. The Mongols preferred Islamic medicine themselves, and also made it available to their subjects through public clinics.” [1] "Other occupational groups fared better under Khubilai than under the Chinese emperors. Physicians were one such group that benefited from Mongolian rule. As a pragmatist, Khubilai valued medicine and accorded doctors a higher social status. He established branches of the Huang-hui ssu (Imperial Hospitals), staffed primarily by Muslim doctors, in K’ai-p’ing and in north China to care for the court. Mongolian officials consulted Muslim physicians, and thirty-six volumes of Muslim medicinal prescriptions were added to the Imperial Library." [2]

"On the contrary, the assertion of continuity with older tradition is combined with the exercise of considerable invention and originality both in materials and iconography, producing some of the most remarkable sculpture in the entire pharaonic corpus. For other spheres of cultural activity there is sometimes an unnerving lacuna in extant material—there are, for example, no literary texts securely dated to this period. For all that, close analysis of such evidence as we do possess confirms that Egyptian society and civilization as a whole were characterized by the same traits as the visual arts. We routinely encounter features with which the student of earlier periods will be completely familiar." [1]

318 Heian present Confident Expert -
’A primary aspect of those beliefs and attitudes is found in the Sukuyodo, "Way of Lodgings and Planetoids," a complex system resulting from a crossing of astronomy with astrology that had occurred in India, but that had been enriched in China before it reached Japan. Almost all Indian science reaching Japan was brought by Buddhist monks, so that astronomy became a primarily Buddhist matter. Monks were not only specialists of metaphysics and philosophy, they also tended to be healers, thaumaturgists, diviners, and astrologers. During the Heian period almost all astronomy and astrology developments that had taken place in various milieus in China were transmitted to Japan by monks of Shingon and Tendai Esoteric Buddhism, so that that form of Buddhism was heavily laden with notions and rituals that belonged originally either to Indian ritual science or to Chinese Taoist and other practices.

363 Kingdom of Norway II present Confident Expert -
’In “Alfræði íslenzk” there are some texts that may be called of a scientific nature. Some were from this period.’ [1] Durrenberger notes the presence of legal and grammatical literature: ’According to most authors writing was introduced to Iceland when the country was Christianized in the year 1000. In the two centuries that followed, writing was used for many purposes: religious works, a grammar, a law book and a short history. Most of the family sagas were written in the thirteenth century. The saga with which I am concerned, Eyrbyggja saga (ÍF 4), is commonly believed to have been written between 1230-1250 (Schach & Hollander 1959:xx). I shall deal only with a part of this saga, which I have called the Þórgunna story (ÍF 4, ch. 49-55). I consider the Þórgunna story a myth. Anthropologists believe that myths contain hidden messages in symbolic forms. According to Malinowski (1926) myths are social charters. Lévi-Strauss (1963) argues that myths have a binary structure and that their oppositions explore contradictions in social and other relations.’ [2] The Grágás legal code is one example: ’It is impossible to say how much of this book is represented in Grágás. Grágás has been preserved in two manuscripts which date to about 1260 and 1280. It is not possible to assign dates to individual provisions within it. The provenance of the manuscripts is unknown and neither is an official compilation (Miller 1990: 42).’ [3]

Entries in the chotmaihet hon are always preceded by a set of numbers indicating the day, lunar date and year of occurrence. The regular motions of the planets were used by the astrologers to establish a system of time-keeping that has been regarded as Siam’s most sophisticated form of temporal measurement. Those responsible for the crafting of the chotmaihet hon were the inheritors and custodians of this complex system. Reflecting their concern with the timing of events, the chotmaihet hon have been known as both calendars and as diaries of the Court Astrologers" [1] "During his restoration of Wat Phrachettuphon (Wat Pho), started in the year of the python, 1832, King Rama III ensured this continuity for many generations to come, by having all available knowledge of the finest quality in the fields of art, letters, technical skills, medicine, and other disciplines engraved on stone plaques and fixed to the walls of the buildings of this Royal wat (temple), so that it would be accessible to all.

"In the field of religion and culture, the nineteenth century is said to have witnessed the golden age of Islam in the Futa Jalon. It was the century of great scholars and the growth of Islamic culture. All the disciplines of the Quran were known and taught: translation, the hadiths, law, apologetics, the ancillary sciences such as grammar, rhetoric, literature, astronomy, local works in Pular and Arabic, and mysticism. Nineteenth-century European visitors were highly impressed by the extent of the Islamization, which was visible in the large number of mosques and schools at all levels, the degree of scholarship, the richness of the libraries, and the widespread practice of Islamic worship. All this seems to have been facilitated by the use of the local language, Pular, as a medium of teaching and popularization of Islamic rules and doctrine." [1]

“The last category is what I have termed "secular" writing, not because it is in any sense neutral towards the discourse of religion, but because the disciplines treated in this literature do not belong to the religious sciences of Islam. The disciplines concerned are the cognitive sciences, logic, and history. In the sciences, while there has been a little writing on mathematical calculation, especially as it relates to the horology (lilm al-mawaqit), and a few works of astronomy or astrology,26 there has been more interest in, and knowledge about, medicine. The earliest work in this category is a small work on the treatment of hemorrhoids by al-Tahir b. Ibrahim al-Fallati of Bornu (fl. 1745), a medical problem also discussed by Muhammad Bello, who wrote as well on the treatment of intestinal worms and on the use of senna as a purgative.” [1]

420 Carnatic Sultanate present Inferred -
The following quote suggests that scientific literature was likely present within the Carnatic Sultanate. “The most significant aspect of South Indian Islam, however, is that it was predominantly influenced by Sufi mysticism. The Sufis were not as bound by doctrinal formalism as the Sunnis or the Shi’ites but were concerned with an individual, mystic devotionalism which made it easy to adapt to the existing religious environment of South India. Sufi mysticism was characterized on the one hand by centres of learning, poetry, science, and on the other hand by the centrality of the pir or saint. The saint’s devotees assembled at his shrine to partake in the sacred power which abounded in the area, thus falling into the existing tradition of sacred places and the importance of pilgrimage.” [1]

[...] Appearing first in the region, the Vai syllabary became the prototype for other writing systems that were created in the inter-wars among indigenous peoples in Sierra Leone and Liberia.

No writing system in Allada the year before Whydah became independent, so likely the same in Whydah: “Another question arising from the incidence of credit in both the local economy and the overseas trade is the nature of the indigenous system of recordkeeping. In Allada the local people, it was noted in 1670, in the absence of writing used knotted strings to keep records of various matters, including commercial transactions (“the price of goods”). Several later accounts allude to other mechanical devices for keeping financial (and fiscal) records in Dahomey.” [1]

434 Early United Mexican States present Confident -
“Men of science and letters took it upon themselves to construct a permanent image of the nation, to draw and set its boundaries, and to name and place its principal geographic and hydrographic features, by setting the nation down on paper. They also sought to articulate, in their writing, a genuine Mexican voice that would characterize a national— and nationalist— literature. It was a grandiose task in which, despite its profoundly political nature, men of all ideological inclinations participated, by presenting their research and lectures before learned societies such as the Ateneo, the literary society of San Juan de Letrán Academy, or the Sociedad Mexicana de Geografía y Estadística. In 1857, the geographer Antonio García Cubas drew on this Society’s previous work to draw up and publish the first general map of the Republic (Craib). These men also collaborated in extensive editorial projects that they felt would contribute to on the one hand consolidating Mexico as a natural entity, and on the other to validating its rightful place among civilized nations. Thus, geographers, historians and philologists who often stood in opposite political trenches, wrote erudite articles on the nation’s demography, its mountainous ranges and its indigenous dialects for the Diccionario Universal de Historia y Geografía, published in Mexico City between 1853 and 1856.” [1]

Science was increasingly popular from the Stuart period, most notably with Charles II being a patron of the sciences. Laboratories and The Royal Society published many scientific papers and books. Sir Francis Bacon wrote Advancement of Learning (1605) which laid the groundwork for scientific method among many other scientific volumes. In 1687 Newton alongside the Royal Society published Principa Mathematica: or the Mathematical Principles of Natural Philosophy. [1] “In order to measure and predict these forces, Newton developed (in parallel with the German scholar Gottfried Wilhelm von Leibniz [1646–1716]) a whole branch of mathematics – calculus. The result was a series of mathematical formulae, supported by observation and experiment, which explained and could be used to predict the movements both of objects on earth, and of the sun, moon, and other heavenly bodies. In 1687, with the assistance of the Royal Society, Newton published his findings in Principia Mathematica: or the Mathematical Principles of Natural Philosophy.” [2]
