The Shape of the World, According to Ancient Maps
A Babylonian clay tablet helped unlock an understanding for how our ancestors saw the world.
Dating all the way back to the 6th century BCE, the Imago Mundi is the oldest known world map, and it offers a unique glimpse into ancient perspectives on earth and the heavens.
While this is the first-known interpretation of such a map, it would certainly not be the last. Today’s visualization, designed by Reddit user PisseGuri82, won the “Best of 2018 Map Contest” for depicting the evolving shapes of man-made maps throughout history.
AD 150: Once Upon A Time in Egypt
In this former location of the Roman Empire, Ptolemy was the first to use positions of latitude and longitude to map countries into his text Geographia. After these ancient maps were lost for centuries, Ptolemy’s work was rediscovered and reconstructed in the 15th century, serving as a foundation for cartography throughout the Middle Ages.
1050: Pointing to the Heavens
The creation of this quintessential medieval T-and-O Beatine map is attributed not to an unknown French monk, but to the Spanish monk Beatus of Liébana. Although it shows several continents—Africa, Asia, and Europe—its main objective was to visualize Biblical locations. For example, because the sun rises in the east, Paradise (The Garden of Eden) can be seen pointing upwards and towards Asia on the map.
1154: The World Turned Upside Down
The Arabic geographer Muhammad al-Idrisi made one of the most advanced medieval world maps for King Roger II of Sicily. The Tabula Rogeriana, which literally translates to “the book of pleasant journeys into faraway lands”, was ahead of the curve compared to contemporaries because it used information from traveler and merchant accounts. The original map was oriented south-up, which is why modern depictions show it upside down.
1375: The Zenith of Medieval Map Work
The Jewish cartographer Abraham Cresques created the most important map of the medieval period, the Catalan Atlas, with his son for Prince John of Aragon. It covers the “East and the West, and everything that, from the Strait [of Gibraltar] leads to the West”. Many Indian and Chinese cities can be identified, based on various voyages by the explorers Marco Polo and Sir John Mandeville.
After this, the Age of Discovery truly began—and maps started to more closely resemble the world map as we know it today.
1489: Feeling Ptolemy and Polo’s Influences
The 15th century was a radical time for map-makers, once Ptolemy’s geographical drawings were re-discovered. Henricus Martellus expanded on Ptolemaic maps, and also relied on sources like Marco Polo’s travels to imagine the Old World. His milestone map closely resembles the oldest-surviving terrestrial globe, Erdapfel, created by cartographer Martin Behaim. Today, it’s preserved at the Yale University archives.
1529: A Well-Kept Spanish Secret
The first ever scientific world map is most widely attributed to the Portuguese cartographer Diego Ribero. The Padrón Real was the Spanish Crown’s official and secret master map, made from hundreds of sailors’ reports of any new lands and their coordinates.
1599: The Wright Idea
English mathematician and cartographer Edward Wright was the first to perfect the Mercator projection—which takes the Earth’s curvature into consideration. Otherwise known as a Wright-Molyneux world map, this linear representation of the earth’s cylindrical map quickly became the standard for navigation.
1778-1832: The Emergence of Modern World Maps
The invention of the marine chronometer transformed marine navigation—as ships were now able to detect both longitude and latitude. Jacques-Nicolas Bellin, a French geographer, was responsible for the 18th century’s highly accurate world maps and nautical charts. His designs favored functionality over the decorative flourishes of cartographers past.
Finally, the German cartographer and lawyer Adolf Stieler was the man behind Stieler’s Handatlas, the leading German world atlas until the mid-20th century. His maps were famous for being updated based on new explorations, making them the most reliable map possible.
Is There Uncharted Territory Left?
It is worth mentioning that these ancient maps above are mostly coming from a European perspective.
That said, the Islamic Golden Age also boasts an impressive cartographic record, reaching its peak partially in thanks to Muhammad al-Idrisi in the 11th century. Similarly, Ancient Chinese empires had a cartographic golden age after the invention of the compass as well.
Does this mean there’s nothing left to explore today? Quite the contrary. While we know so much about our landmasses, the undersea depths remain quite a mystery. In fact, we’ve explored more of outer space than we have 95% of our own oceans.

From Coast to Coast: How U.S. Muni Bonds Help Build the Nation
From the Erie Canal to the Golden Gate Bridge, U.S. municipal bonds have financed crucial infrastructure. This infographic details their long history.
Over 200 Years of U.S. Municipal Bond History
Our modern society shares few characteristics with the 1800s. In the last two centuries, styles have changed, laws have evolved, and cities look entirely different. However, one thing that has prevailed is the way state and local governments finance public projects.
Far from a new invention, municipal bonds have been shaping U.S. communities for more than 200 years. In today’s infographic from New York Life Investments, we take a look back at their long history.
Early Beginnings – 1800s
1812: First Official Issue
New York City issues a general obligation bond for a canal.
1817-1825: Facilitating Economic Growth
A few years later, 42 separate bond issues help fund the successful Erie Canal project.
1843: Growing Popularity
Municipal debt sits at about $25 million. Over the next two decades, this total increases exponentially to fund urban improvement and free public education.
Circa 1865: Railroad Expansion
For a few years after the American Civil War, a great deal of debt is issued to build railroads.
1873: The Panic of 1873
Excessive investment in railroads, real estate, and nonessential services leads to the downfall of the large bank Jay Cooke and Co., smaller firms, and the stock market. Many state and local governments default, temporarily halting municipal financing.
The 20th Century
1913: Exception Granted
U.S. Congress introduces a permanent federal income tax, and specifically excludes municipal bond income from taxation.
Note: today, a portion of municipal bonds are taxable.
1930: Expansion in the West
In the midst of the Great Depression, voters approve $35 million in funding to build the Golden Gate Bridge.
1939-1945: Diverted Resources
With financial resources directed to the military in WWII, municipal debt falls. By 1945, total debt sits at less than $20 billion.
1960: Exponential Growth
Only 25 years later, outstanding public debt—the total amount owed to creditors—more than triples to $66 billion.
1971: Investor Protection
Municipal bond insurance is introduced. That same year, insured municipal bonds finance the construction of hospital facilities in Alaska—bringing essential services and investment opportunities to a remote area.
1975: Marketplace Stewardship
Bringing further reassurance to the municipal bond market, the Municipal Securities Rulemaking Board (MSRB) is introduced to establish regulations for dealers, and for advisors at a later date.
1981: Continued Growth
Outstanding public debt reaches $361 billion.
2009-2010: Economic Recovery
More than $181 billion of federally-subsidized Build America Bonds are issued by state and local governments to help stimulate the economy after the financial crisis.
2016-2018: Investor Dollars at Work
In recent years, state and local debt has financed many important projects across the country.
- 2016: The New York State Thruway Authority issues $850 million in bonds to finance a portion of the new NY Bridge Project.
- 2017: California’s Department of Water Resources issues $428 million in bonds for the maintenance and construction of its water management infrastructure.
- 2018: The Denver International Airport issues $2.5B in bonds to finance capital improvements, the largest airport revenue bond in municipal bond history.
2018: Helping People and the Planet
Sustainable applications for municipal bonds continue to grow, with Californian voters approving $2 billion in financing for supportive housing. In addition, state and local governments issue $4.9 billion in U.S. municipal green bonds.
Today: A Sizable Investment Opportunity
As financing spans the nation, the U.S. municipal bond market is both large and active:
- $3.8 trillion capital market
- One million outstanding securities
- $11.6 billion in par traded per/day
- 40,000 daily trades
Not only that, municipals have offered a compelling after-tax yield. For example, high yield municipals offered 121% of the after-tax yield of high yield corporates as of September 30, 2019.
The Foundation of Infrastructure
For over 200 years, municipal bonds have provided critical financing to build hospitals, schools, highways, airports, and more. Today, two out of three infrastructure projects in the U.S. are financed by municipal bonds.
Additionally, municipals have weathered almost every economic storm, providing much-needed capital stimulus during some of the deepest U.S. recessions. As history continues to unfold, municipals hold great potential for issuers, communities, and investors.
The People’s Republic of China: 70 Years of Economic History
How did China go from agrarian economy to global superpower? This timeline covers the key events and policies that shaped the PRC over its 70-year history.
Chart: 70 Years of China’s Economic Growth
View a high-resolution version of this graphic here.
From agrarian economy to global superpower in half a century—China’s transformation has been an economic success story unlike any other.
Today, China is the world’s second largest economy, making up 16% of $86 trillion global GDP in nominal terms. If you adjust numbers for purchasing power parity (PPP), the Chinese economy has already been the world’s largest since 2014.
The upward trajectory over the last 70 years has been filled with watershed moments, strategic directives, and shocking tragedies — and all of this can be traced back to the founding of the People’s Republic of China (PRC) on October 1st, 1949.
How the PRC Came to Be
The Chinese Civil War (1927–1949) between the Republic of China (ROC) and the Communist Party of China (CPC) caused a fractal split in the nation’s leadership. The CPC emerged victorious, and mainland China was established as the PRC.
Communist leader Mao Zedong set out a few chief goals for the PRC: to overhaul land ownership, to reduce social inequality, and to restore the economy after decades of war. The first State Planning Commission and China’s first 5-year plan were introduced to achieve these goals.
Today’s timely chart looks back on seven decades of notable events and policies that helped shape the country China has become. The base data draws from a graphic by Bert Hofman, the World Bank’s Country Director for China and other Asia-Pacific regions.
The Mao Era: 1949–1977
Mao Zedong’s tenure as Chairman of the PRC triggered sweeping changes for the country.
1953–1957: First 5-Year Plan
The program’s aim was to boost China’s industrialization. Steel production grew four-fold in four years, from 1.3 million tonnes to 5.2 million tonnes. Agricultural output also rose, but it couldn’t keep pace with industrial production.
1958–1962: Great Leap Forward
The campaign emphasized China’s agrarian-to-industrial transformation, via a communal farming system. However, the plan failed—causing an economic breakdown and the deaths of tens of millions in the Great Chinese Famine.
1959–1962: Lushan Conference and 7,000 Cadres meeting
Top leaders in the Chinese Communist Party (CCP) met to create detailed policy frameworks for the PRC’s future.
1966–1976: Great Proletarian Cultural Revolution
Mao Zedong attempted to regain power and support after the failures of the Great Leap Forward. However, this was another plan that backfired, causing millions more deaths by violence and again crippling the Chinese economy.
1971: Joined the United Nations
The PRC replaced the ROC (Taiwan) as a permanent member of the United Nations. This addition also made it one of only five members of the UN Security Council—including the UK, the U.S., France, and Russia.
1972: President Nixon’s visit
After 25 years of radio silence, Richard Nixon was the first sitting U.S. President to step foot into the PRC. This helped re-establish diplomatic relations between the two nations.
1976–1977: Mao Zedong Death, and “Two Whatevers”
After Mao Zedong’s passing, the interim government promised to “resolutely uphold whatever policy decisions Chairman Mao made, and unswervingly follow whatever instructions Chairman Mao gave.”
1979: “One-Child Policy”
The government enacted an aggressive birth-planning program to control the size of the country’s population, which it viewed as growing too fast.
A Wave of Socio-Economic Reforms: 1980-1999
From 1980 onward, China worked on opening up its markets to the outside world, and closing the inequality gap.
1980–1984: Special Economic Zones (SEZs) established
Several cities were designated SEZs, and provided with measures such as tax incentives to attract foreign investment. Today, the economies of cities like Shenzhen have grown to rival the GDPs of entire countries.
1981: National Household Responsibility System implemented
In the Mao era, quotas were set on how many goods farmers could produce, shifting the responsibility of profits to local managers instead. This rapidly increased the standard of living, and the quota system spread from agriculture into other sectors.
1989: Coastal Development Strategy
Post-Mao leadership saw the coastal region as the potential “catalyst” for the entire country’s modernization.
1989–1991: Post-Tiananmen retrenchment
Early 1980s economic reforms had mixed results, and the growing anxiety eventually culminated in a series of protests. After tanks rolled into Tiananmen Square in 1989, the government “retrenched” itself by initially attempting to roll back economic reforms and liberalization. The country’s annual growth plunged from 8.6% between 1979-1989 to 6.5% between 1989-1991.
1990–1991: Shanghai and Shenzhen stock exchanges open
Combined, the Shanghai (SSE) and Shenzhen (SZSE) stock exchanges are worth over $8.5 trillion in total market capitalization today.
1994: Shandong Huaneng lists on the NYSE
The power company was the first PRC enterprise to list on the NYSE. This added a new N-shares group to the existing Chinese capital market options of A-shares, B-shares, and H-shares.
1994–1996: National “8-7” Poverty Reduction Plan
China successfully lifted over 400 million poor people out of poverty between 1981 and 2002 through this endeavor.
1996: “Grasp the Large, Let Go of the Small”
Efforts were made to downsize the state sector. Policy makers were urged to maintain control over state-owned enterprises to “grasp the large”. Meanwhile, the central government was encouraged to relinquish control over smaller SOEs, or “let go of the small”.
1997: Urban Dibao (低保)
China’s social safety net went through restructuring from 1993, and became a nationwide program after strong success in Shanghai.
1997-1999: Hong Kong and Macao handover, Asian Financial Crisis
China was largely unscathed by the regional financial crisis, thanks to the RMB (¥) currency’s non-convertibility. Meanwhile, the PRC regained sovereignty of Hong Kong and Macau back from the UK and Portugal, respectively.
1999: Western Development Strategy
The “Open Up the West” program built out 6 provinces, 5 autonomous regions, and 1 municipality—each becoming integral to the Chinese economy.
Turn of the Century: 2000-present
China’s entry to the World Trade Organization, and the Qualified Foreign Institutional Investor (QFII) program – which let foreign investors participate in the PRC’s stock exchanges – contributed to the country’s economic growth.
2006: Medium-term Plan for Scientific Development
The PRC State Council’s 15-year plan outlines that 2.5% or more of national GDP should be devoted to research and development by 2020.
2008-2009: Global Financial Crisis
The PRC experienced only a mild economic slowdown during the crisis. The country’s GDP growth in 2007 was a staggering 14.2%, but this dropped to 9.7% and 9.5% respectively in the two years following.
2013: Belt and Road Initiative
China’s ambitious plans to develop road, rail, and sea routes across 152 countries is scheduled for completion by 2049—in time for the PRC’s 100th anniversary. More than $900 billion is budgeted for these infrastructure projects.
2015: Made in China 2025
The PRC refuses to be the world’s “factory” any longer. In response, it will invest nearly $300 billion to boost its manufacturing capabilities in high-tech fields like pharmaceuticals, aerospace, and robotics.
Despite the recent ongoing trade dispute with the U.S. and an increasingly aging population, the Chinese growth story seems destined to continue on.
China Paving the Way?
The 70th anniversary of the PRC offers a moment to reflect on the country’s journey from humble beginnings to a powerhouse on the world stage.
Because of China’s economic success, more and more countries see China as an example to emulate, a model of development that could mean moving from rags to riches within a generation.
