One of France's leading history painters in his time, he was equally successful with his decorative paintings, genre scenes and portraits.

His history paintings and mythological scenes were executed in a colourful and fluent style, which was indebted to both Veronese and Peter Paul Rubens.

He made a fresco in the north aisle of the ancient basilica Santi Bonifacio ed Alessio depicting Saint Gerolamo Emiliani introducing orphans to the Virgin.

[5] These pictures depict fashionable people from his time in parks or interior settings who are engaged in courting, card playing, or reading to each other.

While based on the fêtes galantes of Watteau and Nicolas Lancret and on 17th-century Dutch genre painting, de Troy's compositions distinguish themselves through their detailed rendering of clothing and furnishings.

He was able to capture in these compositions the more relaxed behavior of the higher social classes following the death of Louis XIV in 1715 as shown in new fashions and manners.

[1] These compositions are believed to be based on de Troy's personal experiences as he was an active member of the fashionable world he depicted.

In his tapestry designs de Troy abandoned narrative clarity in favour of a profusion of picturesque and anecdotal detail and brilliant colour effects.
