The Blue of Emperors
a colour that meant power

In the palaces of the prince-electors, in the salons of Tsar Peter the Great, at the courts of the Holy Roman Empire — wherever power and taste converged, Delft Blue hung. We make it again, by hand, in the Netherlands.

The history of Caerulea

Why blue was the colour
of gods and emperors

The Romans called it caerulea — the sky blue, the blue of Jupiter himself. It was the colour of the emperor's mantle, the colour of the firmament beneath which his power extended. No colour was more precious, no colour radiated more authority.

Centuries later, in the workshops of Delft, European craftsmen found a way to capture this imperial blue on ceramic. They did so in an attempt to rival the priceless Chinese imperial porcelain — the blue-and-white earthenware made for the exclusive table of the Son of Heaven, considered the most precious object in the world. The Delft craftsmen made no mere copy. They created something new: a wholly European interpretation of an imperial ideal.

The result conquered a continent.

"The taste that united an entire empire — from the prince-elector to the emperor himself."
The philosophy of Caerulea Ars · Delft, 17th century
Three imperial connections

Who coveted the blue gold

Delft Blue was not popular with common people. It was the exclusive possession of the most powerful in Europe. Three imperial stories make this unmistakably clear.

I
China · Ming & Kangxi
The Original Inspiration
The blue-and-white porcelain of the Chinese emperors was the priceless original. Made in imperial workshops for the exclusive table of the Son of Heaven. The Delft craftsmen studied it, admired it and created their own European answer — equally blue, equally elegant, but in the language of the continent.
II
Russia · Peter the Great
The Tsar Who Travelled to Delft
During his famous 'Grand Embassy' journey in 1697–1698, Tsar Peter the Great visited the city of Delft. Delft Blue, then at its absolute peak, fascinated him. He later had his imperial palaces in Russia fitted with tile rooms directly inspired by what he had seen in the Netherlands. The tsar brought the blue to the East.
III
Europe · Holy Roman Empire
The Prince-Electors and the Habsburgs
The most powerful German princes — the prince-electors who chose the Habsburg emperor — competed in magnificence. To demonstrate their status they imported the most coveted earthenware of their time by the thousands: Delft Blue. Their porcelain chambers were the ultimate expression of the imperial lifestyle. What was beloved at their courts defined the taste of an entire continent.
A timeline of power and blue

From Rome to Delft

1st century AD
Rome — Caerulea
The Roman emperors wore the caerulea — the sky blue — as a symbol of divine authority. The colour of Jupiter, the colour of the firmament beneath which their power extended. Blue meant power.
800 AD
Charlemagne — The rebirth of the Empire
Charlemagne is crowned emperor in Rome. The Holy Roman Empire is born — the deliberate and determined resurrection of the Roman legacy. Holy, Roman, Imperial. The dream of Rome refuses to die.
17th century
Delft — The blue gold
In the workshops of Delft, the imperial blue is reborn. Delft Blue conquers the palaces of Europe. Prince-electors order it by the thousands. William III and Mary II decorate Hampton Court with it. It is the colour of the continent.
1697–1698
Peter the Great visits Delft
The tsar who crowns himself the first Russian Emperor makes a pilgrimage to the Netherlands. In Delft he discovers the blue gold. He takes the inspiration to the East and has his palaces fitted in the spirit of what he saw in Delft.

Everything about Caerulea Ars & Delft Blue

What is Delft Blue?+
Delft Blue is hand-painted earthenware from Delft, Netherlands. Characterised by blue decorations on a white background, it was the most coveted earthenware in Europe during the 17th and 18th centuries — the European interpretation of Chinese imperial porcelain, beloved by the highest nobility and rulers of the continent.
What is a Frisian white tile?+
A Frisian white tile is a traditional Dutch wall tile, hand-painted with blue motifs on a white background. The tiles were used extensively in Dutch homes and palaces and are one of the most iconic expressions of the Dutch craft tradition.

During his 'Grand Embassy' journey in 1697–1698, Tsar Peter the Great visited the city of Delft. Delft Blue fascinated him. He later had his palaces in Russia fitted with tile rooms directly inspired by what he had seen in the Netherlands — he brought the imperial blue to the East.
What was the Holy Roman Empire?+
The Holy Roman Empire (circa 800–1806) was the medieval and early modern 'continuation' of the Roman Empire in Central Europe — the name itself claims the direct legacy of Rome. It was led by an emperor, almost always a Habsburg. The prince-electors, the most powerful German princes, elected the emperor. Their palaces, filled with Delft Blue, were the cultural epicentres of the continent.
Why was Delft Blue so popular with the European nobility?+
Delft Blue was the European interpretation of priceless Chinese imperial porcelain. The craftsmen in Delft succeeded in capturing the elegance of the East in a unique, European style. It became the status symbol of the European elite — from the prince-electors of the Holy Roman Empire to Tsar Peter the Great and King William III of England.
Where are Caerulea Ars tiles made?+
All Caerulea Ars tiles are hand-painted in the Netherlands, in the tradition of original Delft Blue and Frisian white tiles. Each piece is unique and finished by hand — no digital printing, no mass production.
What does the name Caerulea Ars mean?+
'Caerulea' is Latin for sky blue, imperial blue — the colour reserved for gods and emperors in ancient Rome. 'Ars' is Latin for art and craftsmanship. Caerulea Ars: the art of imperial blue.
“This object is not the product of a single court, but a symbol of the taste that united the elite of an entire empire — from the prince-elector to the emperor himself.”
