Jacques de Cambrai (fl. c. 1260–80), sometimes Jaque or Jaikes, was a trouvère from Cambrai. He composed four chansons courtoises, one pastourelle, six devotional chansons, and one Marian rotrouenge. The Berne manuscript preserves all his works, nine of them uniquely. In addition, a chanson and the pastourelle are preserved in the manuscript Oxford Douce 308 and one of the devotional songs is also copied in two other sources.[1] The Berne manuscript notes that his Haute dame, com rose et lis was modelled on (i.e. a contrafactum of) Ausi com l'unicorne sui by Theobald I of Navarre and Mere, douce creature on Quant voi la glaie meure by Raoul de Soissons. Otherwise none of his music survives, though staves for its transcription were prepared. Of all Jacques's works, only his rotrouenge, the Retrowange novelle, has no model mentioned in the manuscripts; its rubric reads only "Jaikes de Cambrai—De Notre Dame" (Jaque of Cambrai—On Our Lady).
Jacques's devotional songs emphasise Jesus' humanity and his Passion. These may be directed at the Cathars, who denied Christ's humanity. Jacques was one of the last medieval French poets to express his devotion to Mary primarily through chansons, that is, modelled on the chansons courtoises or love songs. After him the tendency was to use the serventois and even later the chant royal.
