 Both unpublished texts were still in poor condition when Descartes died in 1650. Among other deficiencies, they lacked most of the diagrams that were required to make his theory intelligible to readers, which Descartes had been unable to draw. Since Clerselier was equally incapable of providing adequate illustrations, he invited various people to prepare them. A number of those who understood Cartesian physiology (including Henricus Regius) refused to cooperate. Clerselier eventually identified two willing collaborators; one was Louis de la Forge, in Saumur, and the other was Gerard van Gutschoven (1615–68), a professor of anatomy in Louvain. Clerselier accepted both offers of assistance and published their illustrations in the first edition. When the results of their artistic efforts coincided, he usually preferred those of Gutschoven because they were better drawn; however, when they differed, he published both and used the letters ‘F’ and ‘G’ to identify their respective authors. La Forge was thus credited with seven of the published illustrations. Descartes’ Traité de l’Homme, with these illustrations and extensive notes by La Forge, was published in Paris in April 1664. Thus La Forge’s first publication was the lengthy set of notes that explain various features of Descartes’ Traité, which appeared as Remarques on pp. 171–408 of the first French edition of that work. Meantime, Florentius Schuyl (1619­–69) had already published independently a Latin translation of the manuscript of the Traité in 1662, under the title De Homine (Descartes 1662).
