The talk on bee-keeping and ley-lines that Borry mentioned had such an angry reception from Kennet Beekeepers Association that I reckon there must have been some kind of cognitive dissonance at work
http://www.bbka.org.uk/members/forum.php?t=5433 It's surely the case that before large-scale sugar plantations, honey was the main source of sweetness and therefore a desirable commodity. Most of the villages, estates and monasteries on and near main roads would presumably have had beehives, for trade purposes if not for themselves. All main roads aren't neccessarily former ley-lines but as a rule of thumb, main roads are traditional trade/droving routes.
Actually my interest was aroused because the map of Spain shows an almost completely straight route runs from Gijon in the north to Cadiz in the south, more or less tracing the 'Gijon Meridian' that we discussed. Roughly halfway along the north-south route is the village of Bejar which apparently means 'place of bees', from
abeja (bee). A medieval legend relates how Christians during the Reconquista disguised themselves as moss-covered beehives and got past the Muslim defenders, like a Trojan horse story.
On the cherchez the saint principle, I found several patron saints of beekeeping, foremost of which seems to be St Gobnait or Abigail, purely on the basis of her name (cf. abeille i.e. bee) as was the case for St Ambrose; Gobnait is said to have been a patron saint of ironworkers [
gobba,
gabha, ‘smith’].
