(Haarlem circa 1589–um 1640 The Hague)
A forest path. 1618–20.
Oil on canvas on panel. 16 × 22.4 cm.
Estimate: CHF 350 000 / 500 000
Auction on 22 March 2024

This landscape is a significant addition to the very few known oil paintings by Hercules Segers, an important Dutch artist of the Golden Age. Although a number of forest paintings by Segers are mentioned in old sources, this depiction of a winding forest path is the only surviving example of this genre by the artist.

Documented in several early inventories, its recent rediscovery in a Norwegian private collection is the result of art-historical detective work and fortunate circumstances.

Another successful, exciting and diverse auction season has drawn to a close. The classic collecting fields which we have been offering for several decades, such as old master paintings, Swiss art, and modern and contemporary art enjoyed good results. We also were entrusted with several high-calibre private collections in 2023, among them the Legrain Collection, with exquisite sculptures and objects from Greco-Roman and Egyptian antiquity.

Our auctions continue to focus on fine art, jewellery, wristwatches, decorative arts and Asian art, which have been an integral part of our auction programme for many years. At the same time, new categories have been met with great interest, especially among collectors of traditional art. In our new ‘Out of This World’ auctions, for example, within the past year we sold fossils of two of the most iconic dinosaurs: a Tyrannosaurus rex and a young Triceratops.

On the following pages you will find some of the highlights of the past auction year; the images and results speak for themselves. Further information about our past and future auctions can be found on our website.

We would like to thank you for continuing to place your trust in us in 2023 and wish you confidence, happiness and good health for the New Year.


The T. rex 'Trinity' will be exhibited in the Dinosaur Museum in Aathal, Switzerland

Sauriermuseum Aathal, Zürichstrasse 69,
8607 Aathal, Switzerland
Tel. +41 44 932 14 18,

TRX-293 TRINITY, the world-famous Tyrannosaurus rex skeleton that the Phoebus Foundation purchased at Koller Auctions in April 2023, will be exhibited at the Dinosaur Museum in Aathal, Switzerland, for one year beginning on 23 January 2024.

It will be several years before Trinity's permanent home – an Art Deco skyscraper in the heart of Antwerp that the Phoebus Foundation is transforming into an international arts centre designed by the renowned architect Daniel Libeskind – will be ready to house the gigantic fossil. In the meantime, the Phoebus Foundation wanted Trinity to be available to the public and for scientific research, and the Dinosaur Museum will be the first museum to display Trinity during this period, thanks to the initiative and mediation of Koller Auctions and Christian Link's Wunderkammer.

After enchanting tens of thousands of visitors during the pre-auction exhibition organised by Koller and Wunderkammer at the Zurich Tonhalle concert hall last spring, Trinity will soon be the star of the Aathal museum from late January 2024, for approximately one year. The team of the Dinosaur Museum was responsible for the construction of Trinity for the Tonhalle exhibition, and gave generously of their technical expertise throughout the cataloguing process. 'We are thrilled to welcome Trinity to our museum and to allow the public as well as the scientific community to spend time with this magnificent specimen', said Dr Hans-Jakob Siber, founder and director of the Dinosaur Museum. 'We have already spent so much time with this dinosaur that in a way it feels like welcoming back an old friend'.

Dr Katharina Van Cauteren, Chief of Staff of the Chancellery of the Phoebus Foundation, said, 'We are delighted to be working with the Dinosaur Museum. Trinity will be exhibited here amongst many other impressive dinosaurs, giving the public a unique opportunity to see the T. rex in context. At the same time, scientific research is being carried out that will allow us to learn even more about the find. Of course, we will also share this new information with the public as the project progresses. This is the beginning of an exciting new life for this ancient skeleton'.

A thousand grains of sand – Joseph Werner’s 'Apollo and the Cumaean Sibyl'

Apollo and the Cumaean Sibyl
Oil on copper. 18.5 × 13.4 cm.
Estimate: CHF 30 000 / 50 000
Auction: 23 September 2023
Click on the image for further information

This charming small-format painting depicts a scene not often represented in art: Apollo and the Cumaean Sibyl. The Sibyls were women with a special gift for predicting the future, associated with various temples in the ancient world. The Cumaean Sibyl’s temple was that of Apollo, near Naples. Ovid, in his ‘Metamorphoses’, recounts how the god himself approached her, desiring to take her virginity, in exchange for which he would grant her any wish.

Mummy portraits, or ‘Fayum’ portraits as they are often called, are realistically painted likenesses which were placed over the faces of mummies in parts of Egypt from the 1st to 3rd centuries CE. Although they were first discovered by Europeans in 1615, it wasn’t until the late 19th century that these portraits entered popular awareness. In 1887, an Austrian carpet and textile dealer, Theodor Graf (1840–1903), was in Cairo looking for rare textiles when he was offered several hundred such portraits. He bought them all, and selected about ninety to include in a selling exhibition that travelled throughout Europe and America, including the Chicago World’s Fair in 1893.

After a pause of three years due to the pandemic, Koller's Asian Art department was able to once again exhibit highlights from the upcoming June auctions at the prestigious International Fine Arts Fair (IAF) in Hong Kong from 27 to 30 May 2023.

The fair was particularly well-visited this year, and large numbers of collectors were present at Koller's exhibition space during the preview as well as the fair's four-day run.

The excellent turnout and reactions from the public bode well for the June Asian Art auctions as well as for Koller's continued presence in East Asia.

Asian Art auction catalogues



The buyer of Trinity, the Tyrannosaurus rex skeleton sold for CHF 5.5 million ($6 million) at Koller Auctions in Zurich on 18 April, is The Phoebus Foundation, a non-profit art foundation. Phoebus has announced their intention to show Trinity to the public in their ‘Boerentoren’ cultural centre project in Antwerp, designed by Daniel Libeskind.

The Boerentoren (literally translated as ‘Farmer’s Tower’, a nickname that stuck) was the first skyscraper in Europe, completed in 1931. In 2021, the tower, originally constructed as an office building with apartments, was purchased by The Phoebus Foundation, which will turn it into a public space in a few years. The entire building will be dedicated to culture, with extensive space for temporary and long-term exhibitions, a sculpture garden and a panoramic viewpoint, as well as numerous culinary experiences. Daniel Libeskind is currently working on the final designs to convert what remains of the original art deco building into a truly unique architectural landmark. The addition of Trinity to the collection of The Phoebus Foundation will only add to the Boerentoren’s appeal.

Trinity already enchanted approximately 35 000 visitors during a three-week exhibition at the Tonhalle concert hall in Zurich, and has been featured in countless press articles, television and radio broadcasts and blogs worldwide.

VICTOR VASARELY, Karpat. 1984.
Acrylic on canvas. 84 × 84 cm.
Sold for CHF 116 000 in December 2021
Click on the image for more details.

Instead of choosing between painting or sculpture, some post-war artists decided to push the boundaries between the two, creating two-dimensional works which also explore the possibilities offered by sculpture. Victor Vasarely spent much of his career experimenting with carefully crafted, illusionistic effects which made the motif shimmer, spin, or appear to extend from the canvas into the viewer’s space, as in his 1984 work, ‘Karpat’. As with sculpture, a key element in Vasarely’s work is that the perception of the artwork changes with the spectator’s point of view. Jesús Rafael Soto utilised a similar concept in his work ‘Vibrations’, 1967, in which the lines screenprinted onto a plastic sheet appear to float in front of a striped and seemingly vibrating background.

MAURICE DENIS, Bacchanale, esquisse 3. 1920.
Oil on board. 36,7 × 55,8 cm.
Sold for CHF 40 000 in December 2021
Click on the image for more details.

When Maurice Denis painted ‘La Bacchanale du Tigre Royal’ in 1920, he was at a pivotal moment in his personal and professional life. His beloved wife for 26 years, Marthe, had passed away the previous year. His artistic career was also taking a new direction. Denis’ work after the First World War was dominated by mural painting. A devout Catholic, he co-founded the Ateliers de l’Art Sacré in 1919 to promote Christian art, training artists and craftsmen with this goal in mind. The group mainly executed murals and stained glass for churches, many of which had been damaged during the war. Already in 1916, Denis had set his sights the ‘supreme goal of painting, which is the large-scale decorative mural’. By the end of his life he had executed twenty murals and numerous large-format canvasses, including ‘La Bacchanale’.

Frederick II's elephant, depicted in an imperial procession in Cremona in 1237. (Matthew Paris, 'Cronica Maiora', Part II, Parker Library, MS 16, fol. 151V).
Click on the image for more details.

Collecting exotic and domestic animals for display was a pastime and a symbol of prestige and power for European monarchs for centuries.

Holy Roman Emperor Frederick II exchanged a series of rare beasts with Al-Malik al-Kamil, sultan of Egypt, in the early 13th century. Al-Kamil sent an elephant to Frederick, as well as a white cockatoo from Australasia – a region that was completely unknown to the Western world at that time, so the bird would have been exceedingly rare. In return, Frederick’s gifts to the Sultan included horses with gem-incrusted golden stirrups, a white peacock, and a white bear.

JEAN-BAPTISTE GREUZE, Portrait of a child, probably Prince Octavius of Great Britain.
Oil on panel. 17,5 cm × 14,5 cm.
Sold for CHF 49 0000
Click on the image for more details.

Determining the identity of the sitter in a portrait often involves what resembles detective work – clues are gathered, inferences made, and sometimes a likely identification can be made. In the case of the little boy depicted by Jean-Baptiste Greuze offered here, we do have two clues.

The first is a label which was originally on the back of the panel, inscribed ‘Eigenthum Ihrer Majestät der Königin Mathilde von Württemberg’ (Property of Her Majesty Queen Mathilde of Württemberg). Charlotte Mathilde was the eldest daughter of King George III of Britain and his queen consort, Charlotte. The fact that this painting was in Charlotte Mathilde’s possession means that she not only took it with her when she married Frederick, future king of Württemberg when she was 33 years old, but also to Ludwigsburg Palace near Stuttgart when she settled there as dowager queen after Frederick’s death. To have kept this small portrait among her personal property during her entire life, the sitter must have meant a great deal to her.

Such birdcage automatons were often created as a collaboration of various specialized watchmakers and automaton makers from Neuchâtel and the Jura. They are witnesses of great skill and enjoyed great popularity in the period between 1780 and 1840. Among the most important watchmaking dynasties are the Robert, Jaquet-Droz, Frédéric Leschot, Maillardet, Fochat and Bruguier families. Others, such as François Nicole and Charles-Frédéric Nardin, specialized in the making of music boxes. The luxury objects resulting from this collaboration were often sold to the European aristocracy as well as to China, Russia, and the Ottoman Empire through Geneva-based makers and sellers, such as Jean-François Bautte (1772-1837), who signed the clock on offer. The founding of Bautte & Moynier dates back to 1791, when case maker Jean-François Bautte joined forces with watchmaker Dauphin Moulinié. The company was expanded in 1804 when watchmaker Jean-Gabriel Moynier joined, and thereafter operated as Moulinié, Bautte & Moynier, fabrique d'horlogerie. The luxury company employed about 60 workers and produced watches as well as jewelry of the highest quality. Bautte became one of the most important watch dealers in Geneva. After the departure of Moulinié around 1824, the name was changed to Bautte & Moynier.

Ein bedeutendes kaiserliches Objekt aus China unter dem Hammer

Die beeindruckend geschnitzte Palastwand wurde Recherchen zu Folge sehr wahrscheinlich für die Räumlichkeiten der Kaiserwitwe Cixi (1835–1908) angefertigt. Die beidseitig kunstvoll durchbrochene Wand ist ein charakteristisches Beispiel für die Innenausstattung der kaiserlichen Paläste der Qing-Zeit. Aus Peking sind zwei weitere vergleichbare Objekte mit oktogonaler Türöffnung bekannt: ein Raumteiler befand sich im Yiluandian Palast, wurde aber 1901 bei einem Brand vollständig zerstört. Die zweite Wand befindet sich in einem Wohngebäude im westlichen Teil der Verbotenen Stadt. Bei der hier ange botenen Trennwand handelte es sich um das einzige je auf dem weltweiten Kunstmarkt angebotene Kunstwerk dieser Art. Für 940’000 Franken gelangte es nun in asiatischen Besitz.
