Long before electricity, fountains were a common feature of public spaces. The earliest known fountain, a carved stone basin, is believed to be from around 2000 BC. Fountains in ancient civilizations relied on gravity to control the flow of water, with water sourced from aqueducts, streams, and rivers. These early fountains were often functional, serving as a source of drinking water, but they could also hold religious and ceremonial significance. By the first century BC, Roman fountains were jetting water into the air via water pressure from distant sources. The ancient Romans had an elaborate system of aqueducts supplying water to the many decorative fountains throughout each city. These fountains were often bronze or stone masks of animals, local figures, and mythological heroes. Fountains continued to be a prominent feature of public spaces through the Middle Ages, Renaissance, and Baroque eras, with new innovations in lighting and water pressure emerging over time.

What You'll Learn
Gravity and pressure
The functioning of fountains before electricity depended on gravity and pressure. Water flows due to gravity, which displaces air in the first container, then flows into a second container, displacing the water there. The height of the water source is crucial, as it generates the pressure required for the fountain to operate. A higher source, like the Triton Fountain, can propel water upwards, while a lower source, such as the Trevi Fountain, results in water flowing downwards.
In ancient Rome, public fountains functioned without motors, utilising gravity-fed water from aqueducts that transported water from surrounding hills into the city. The water was stored in large cisterns, which provided the necessary height to create water pressure. The elevation of the cistern alone was sufficient to generate water pressure, with each foot of height creating 0.43 psi. This allowed fountains to spray water without mechanical pumps.
Similarly, the fountains of Versailles relied on water from reservoirs located just above them. King Louis XIV constructed an extensive complex of pumps, the Machine de Marly, to raise water 162 meters above the Seine River to these reservoirs. The Machine de Marly featured 14 water wheels, each 12 meters in diameter, powering 257 pumps.
Prior to the advent of electric pumps, fountains were often powered by water wheels in nearby rivers or through manual labour, with people hired to transport water upwards.

Water collection and transportation
Water Collection
- Natural Sources: Water was collected from natural sources such as rivers, streams, or springs. These sources provided a continuous supply of water that could be directed towards the fountains.
- Aqueducts: Ancient civilizations like the Romans constructed aqueducts to transport water from surrounding hills or distant sources to the city. These aqueducts used gravity to move water downhill, ensuring a steady flow.
- Reservoirs and Cisterns: Water was collected and stored in reservoirs or cisterns located at higher elevations. These served as intermediate storage points, providing the necessary height to create water pressure for the fountains.
Water Transportation
- Gravity and Pressure: The basic principle behind fountain operation was gravity and pressure. Water flowed due to gravity, displacing air and creating a vacuum that pulled more water down.
- Water Wheels: Water wheels were used to pump water to higher levels. In the case of Versailles, Louis XIV utilized an array of 14 large water wheels, each 12 meters in diameter, to power pumping stations and distribute water through aqueducts and pipes.
- Manual Labour: In some cases, manual labour was employed to transport water. A group of people would carry or lift water containers to fill the fountain, demonstrating the amount of power and wealth a ruler possessed.

Power and status
Flowing water was a symbol of power and status in ancient times. Fountains served as a tangible display of wealth, requiring a significant amount of water, which was often transported upwards, creating a sense of awe and wonder. The construction and maintenance of fountains demanded a considerable investment of resources, manpower, and technological expertise, making them exclusive to the wealthy and powerful.
The fountains of Versailles, constructed by Louis XIV, are a prime example of the connection between fountains and power. Louis XIV chose to associate himself with Apollo, the sun god, earning him the title of "Sun King." To showcase his wealth and impress foreign delegates, he built an extensive complex of pumps, known as the Machine de Marly, with 14 water wheels and 220 pumps, to raise water 162 meters above the Seine River to supply his fountains. The sheer scale and grandeur of these fountains were a testament to the purchasing power and technological prowess of the French monarchy.
Similarly, the fountains in Ancient Rome showcased the engineering prowess and power of the Roman Empire. These fountains utilized gravity-fed water from aqueducts, which transported water from surrounding hills into the city. The water was stored in large cisterns, providing the necessary height and pressure for the fountains to operate without the need for mechanical pumps. The ability to supply water to the entire city and create decorative fountains was a demonstration of Roman engineering skills and a symbol of their dominance.
The psychological impact of these impressive displays of water and engineering was significant. Rulers used fountains as a form of psychological warfare, intimidating enemies and solidifying their power. The fountains became a way to assert dominance and showcase their wealth and purchasing power, which could be translated into military might.
The connection between fountains and power was not limited to ancient times. Even during the reign of Louis XVI, over a hundred years after Louis XIV, the French monarchy continued to display royal extravagance through the construction of fountains. However, this excessive display of wealth eventually led to the revolution, as the French people grew tired of the monarchy's conspicuous consumption.

Aesthetics and functionality
Fountains have been built for centuries, with some of the most famous and impressive examples constructed before the widespread use of electricity. These ancient fountains showcase remarkable engineering and artistic achievements, serving both functional and decorative purposes. The functionality of fountains lies in their ability to provide a reliable source of water for practical use, while their aesthetics are enhanced by the beauty of flowing water, often combined with intricate designs and dramatic presentations.
The functionality of fountains before electricity centred on the utilisation of gravity and water pressure. Ancient fountains, such as those in Rome, relied on gravity-fed water from aqueducts or nearby rivers. The water was transported from higher elevations, such as surrounding hills, and stored in large cisterns. The height of the water source was crucial, as it generated water pressure, allowing the fountains to spray or pour water without the need for mechanical pumps. Each foot of height provided approximately 0.43 pounds per square inch (psi) of water pressure. This principle is similar to that of modern water towers, where water is stored at an elevated level to maintain water pressure in distribution systems.
The aesthetics of fountains were enhanced by the creative use of water and the incorporation of artistic elements. For instance, the Trevi Fountain in Rome was designed with a lower water source, resulting in water pouring downwards, creating a dramatic effect. On the other hand, the Triton Fountain, with its higher water source, could shoot water up to 16 feet (4.9 metres) in the air. The fountains of Versailles, constructed by Louis XIV, were known for their artistic triumph and served as instruments of international policy, showcasing the purchasing power of the French regime. The fountains' intricate designs and the sheer manpower and pump technology required to operate them left a lasting impression on foreign delegates.
In addition to the visual appeal of flowing water, some fountains incorporated illumination to enhance their aesthetics.
