Domenico Theotokopuli, nicknamed El Greco, was born on the island of Crete. In the second half of the 16th century, he moved to Italy, from where in 1576 he left for Spain, where he lived until his death. In the canvases of the master, subjectivism in the worldview prevails over reality. As a rule, the heroes of his paintings are placed in surreal mysterious worlds. El Greco often depicted saints.

In the image of a page for this work, the artist captured his son Jorge Manuel. The figure of Louis IX, canonized by the Catholic Church in 1297, is made in his characteristic manner with elongated proportions, as if directed upwards, towards God, emphasizing the height of the spirit of the depicted person. The sad deep look of beautiful dark eyes on a thin face, which stands out for its pallor in the general color of the work, speaks of the deep inner life of Louis.
