⁷ Clulee, N. H., ‘Astrology, magic, and optics: facets of John Dee's early natural philosophy’, Renaissance quarterly, 1977, 30, 632–80 (642)CrossRefGoogle ScholarPubMed, dates Dee's interest in Roger Bacon to 1556. Clulee's valuable article is much concerned with the Propaedeumata, but presumably appeared too late to be included in Heilbron's and Shumaker's bibliography.
