A Philosopher Lecturing on the Orrery

• 1. Light And The Solar Model

  ›

  The year 1766 marked the creation of a painting that replaced the sun with a single lamp. Joseph Wright of Derby placed this artificial light at the center of a mechanical model called an orrery. Shadows stretched across the faces of the small audience gathered in the dark room. This lighting choice was not merely decorative but essential to the demonstration itself. The flickering flame cast moving shadows on the walls and the figures. Goethe later described viewing sculpture by candlelight as a fashionable practice where contours showed well. Wright used this effect to create a sense of movement from the static objects. The lamp represented the sun while the planets moved around it in a precise mechanical dance. The darkness surrounding the group heightened the drama of the scientific display.

• 2. Breaking Classical Traditions

  ›

  Wright chose to replace a classical subject with one of a scientific nature for his next major work. Previous traditions reserved artistic depictions of wonder for religious events alone. He believed the marvels of the technological age were just as awe-inspiring as great religious paintings. An anonymous review from the time called him a very great and uncommon genius in a peculiar way. The painting challenged the rigid French-dictated hierarchy of genres in late 18th century Britain. Other types of painting began to aspire to be treated seriously alongside costumed history painting. These works resembled conversation pieces which were then largely a form of middle-class portraiture. Yet their solemn atmosphere meant they could not be regarded simply as portraits even if models might be identified. Ellis Waterhouse compared these two works to the genre serieux of contemporary French drama defined by Denis Diderot.

• 3. The Candlelit Style Emerges

  ›

  Three Persons Viewing the Gladiator by Candlelight was painted in 1765 before this Orrery piece. That earlier work showed three men studying a small copy of the Borghese Gladiator under candlelight. The Borghese Gladiator was greatly admired but the Orrery caused a greater stir among viewers. Wright established his signature use of chiaroscuro for modern themes through these experiments. There seems no reason other than heightened drama to stage the air pump experiment in a room lit by a single candle. Charles-Amédée-Philippe van Loo later painted similar subjects with normal lighting instead. The shadows cast by the lamp representing the sun were an essential part of the display. This realist justification allowed the viewer to see contours clearly while creating an impression of movement from the flickering light.

• 4. Ownership And The Earl

  ›

  The Orrery was painted without a commission probably in expectation that it would be bought by Washington Shirley. He held the title of 5th Earl Ferrers and was a British Royal Navy officer who owned an orrery himself. Peter Perez Burdett was staying with Ferrers while in Derbyshire when Wright began working on the piece. Figures thought to be portraits of Burdett and Ferrers feature in the painting itself. Burdett takes notes while Ferrers sits seated with a youth next to the orrery. Ferrers purchased the painting for £210 at the Exhibition of 1766 of the Society of Artists. The 6th Earl later auctioned it off before it entered public collection. It now resides in the Derby Museum and Art Gallery where it is on permanent display close to a working replica.

• 5. Identifying The Faces

  ›

  Benedict Nicolson argued in 1968 that John Whitehurst was the model for the lecturer figure. Another commentator points out the figure's resemblance to a painting of Isaac Newton by Godfrey Kneller. Close observation of the adult faces reveals each one demonstrates one or other of the main phases of the Moon. These phases include new moon half moon gibbous moon and full moon. Jonathan Powers claims that the Philosopher was John Arden a scholar best known for teaching the young Mary Wollstonecraft. The debate continues over whether these characters represent specific historical scientists or generic types. No single identification has been universally accepted by art historians despite the detailed study of the faces.

• 6. Replica And Modern Display

  ›

  A working reconstruction of the grand orrery depicted in Joseph Wright's painting was commissioned by Derby Museums in 1993. Clock and orrery-maker John Gleave built this mechanical device to stand alongside the original work. The museum displays the replica next to the painting in its art gallery. Visitors can see the actual painting from 1766 while observing how the machine functions today. This arrangement allows the public to understand both the artistic vision and the scientific reality behind the scene. The painting is now housed in the Derby Museum and Art Gallery where it remains on permanent display. The combination of the artwork and the functional model provides a complete view of Wright's achievement.
