Please answer the following question: What are the last names of the French critics who promoted the painter who had only a few copies of his works produced?  Answer the above question based on the context below:  El Greco was disdained by the immediate generations after his death because his work was opposed in many respects to the principles of the early baroque style which came to the fore near the beginning of the 17th century and soon supplanted the last surviving traits of the 16th-century Mannerism. El Greco was deemed incomprehensible and had no important followers. Only his son and a few unknown painters produced weak copies of his works. Late 17th- and early 18th-century Spanish commentators praised his skill but criticized his antinaturalistic style and his complex iconography. Some of these commentators, such as Antonio Palomino and Juan Agustín Ceán Bermúdez, described his mature work as "contemptible", "ridiculous" and "worthy of scorn". The views of Palomino and Bermúdez were frequently repeated in Spanish historiography, adorned with terms such as "strange", "queer", "original", "eccentric" and "odd". The phrase "sunk in eccentricity", often encountered in such texts, in time developed into "madness".With the arrival of Romantic sentiments in the late 18th century, El Greco's works were examined anew. To French writer Théophile Gautier, El Greco was the precursor of the European Romantic movement in all its craving for the strange and the extreme. Gautier regarded El Greco as the ideal romantic hero (the "gifted", the "misunderstood", the "mad"), and was the first who explicitly expressed his admiration for El Greco's later technique. French art critics Zacharie Astruc and Paul Lefort helped to promote a widespread revival of interest in his painting. In the 1890s, Spanish painters living in Paris adopted him as their guide and mentor. However, in the popular English-speaking imagination he remained the man who "painted horrors in the Escorial" in the words of Ephraim Chambers' Cyclopaedia in 1899.In 1908, Spanish art historian Manuel Bartolomé Cossío published the first comprehensive catalogue of El Greco's works; in this book El Greco was presented as the founder of the Spanish School.
