35. Scholars of medieval science have identified at least three early Euclid texts, known by convention as Adelard I, Adelard II, and Adelard III. Textual analysis, cross-references, and other clues have fueled a lively debate that continues to run. Marshall Clagett first established the basic approach. See Clagett, “The Medieval Latin Translations from the Arabic of the Elements of Euclid, with Special Emphasis on the Versions of Adelard of Bath,” Isis 44 (1953): 16–42.
For further studies and contrasting views, see Busard, First Latin Translation; Richard Lorch, “Some Remarks on the Arabic-Latin Euclid,” and Menso Folkerts, “Adelard’s Version of Euclid’s Elements,” both in Adelard of Bath: An English Scientist, 45–54; and Busard and Folkerts, Robert of Chester’s (?) Redaction of Euclid’s Elements, the So~called Adelard II Version, 2vols. (Basel, Switzerland: Birkhauser Cerlag, 1992).

45. French and Cunningham, Before Science, 232. French and Cunningham go on to argue that Robert’s interest in geometry with respect to nature is not about measuring and calculating, but about extending his neoplatonic view of nature. Nonetheless, the introduction of geometry to discussions of nature marked an important development in the emergence of scientific thinking. For more on Robert’s innovations in the early scientific method, see A. C. Crombie, Robert Grosseteste and the Origins of Experimental Science, 1100–1700 (Oxford: Clarendon Press, 1971).

73. Charles Burnett has suggested that perhaps Adelard’s level of Arabic was very low or virtually nil and that he relied on Arab informants and teachers rather than Arabic texts. This is difficult to square with some of the translations ascribed to Adelard, which Burnett and others generally accept, although it might have been possible with the help of reliable intermediaries. Still, the case “against” Adelard relies heavily on the absence of written Arabic material in some of his surviving works. Adelard’s crucial role as a transmitter of Arabic learning, as well as his revolutionary stance on the importance of direct experience and reason over written authority, remains untouched by any debate over his level of linguistic skill. See Burnett, “Adelard of Bath and the Arabs,” in Rencontres de cultures dans la philosophie medievale (Louvain-la-Neuve: Cassino, 1990): 89–107.

16. There has been considerable scholarly debate about the date of On the Use of the Astrolabe. Its apparent dedication to Prince Henry Plantagenet, the future Henry II, at “the age of discretion” would suggest Henry was around sixteen years old at the time. That would place the work around 1149 or 1150. For this view, see Dickey, “Adelard of Bath,” 64–70 (see chap. 2, n. 28). Charles Homer Haskins prefers somewhat earlier, 1142–1146. See Haskins, Studies, 28–29 (see chap. 5, n. 3). It was clearly one of Adelard’s later works, for it refers to several of his earlier texts and assumes the reader is familiar with them.
