Gower’sÂ fifteen stars, stones, and herbs are illustrated in a fifteenth-century copy (Pierpont Morgan MS M.126). Here’s a leaf containing passages we took note ofÂ in seminar. It’s as good as any for underscoring the vibrancyÂ and interanimation of elements (from the micro to the macro, the nearby and faraway)!
Here is a magnified view of theÂ illustration of Sirius, beryl, and savin:
To learn more,Â take a look at Tamara O’Callaghan’s chapter inÂ John Gower, Trilingual Poet: Language, Translation, and Tradition, ed. Dutton. She locatesÂ the source of such lore (astronomical, lapidary, herbal) in Hermetic and Arabic sources as well as in Dante, and she goes through the illustrations in the Pierpont Morgan MS. A greatÂ model of scholarship on vernacularÂ sciences and literary culture.
Totipotential cell life (blastomeres) in the fertilized ovum.
As we will observeÂ this week, the general situation of gestation and growth can be understood as a virtual condition, adopting the medieval Latin coinage virtualis (strength, potency, effectiveness), employed in highly specialized senses by the schoolmen, cosmographers, and poets and other wanderers, and taken up recently again by several contemporary thinkers (Spinoza, Deleuze, DeLanda, etc.). The idea remained at a highÂ level of abstraction in scholastic debate, but various associations hovered around the word vertu (in French, Italian, or English), describing concrete scenes of springtime efflorescence, planetary influence, and human generation. At some point we may address the notion in Chaucer’s General Prologue.
As we witness this week, the term crops up repeatedly in discussions of embryology — most famously, in Danteâ€™s â€œvirtute informativa,” which is the power of an organism to reproduce itself by means of an active force inherent in blood that becomes semen, which when it is mingled with female matter in the womb is further shaped by animal force, â€œvirtute attiva,â€ thereafter receiving a human spirit replete with virtue, â€œdi vertÃ¹ repleteâ€ (PurgatoryÂ XXV). Giles of Rome and Bartholomaeus Anglicus among others in the course of their scientific discussions use the terminology expressly in speaking about the seed or soul acting â€œvirtually.” Â It would seem to be one of the sites ofÂ emergentÂ immmaterialityÂ that is materialized at different spatiotemporal scales, and the very mainspring ofÂ materiality. The virtual is that which enables matter to attain successive states of animation or vivification, and so cannot be identified exactly with some past or present state, matter or non-matter, but — and here we must interpret for ourselves, straining toÂ find words to express what lies outside of human categories — it is like a dynamic potentiality that penetrates into or throughÂ matter.
If you’re at all drawn in by these ideas, see also Massumi’s Parables of the Virtual.Â
ForÂ a beautiful account of vertuÂ in medieval contexts take a look at Jeffrey J. Cohen’s “An abecedarium for the elements” fromÂ a recent issue of postmedieval.
