@Amulet OK, this is the last of my 'Wyrd Sisters' citation: The duke often mused on his good luck in marrying her. If it wasn’t for the engine of her ambition he’d be just another local lord, with nothing much to do but hunt, drink and exercise his droit de seigneur. -- Wyrd Sisters, Terry Pratchett's sixth Discworld novel, 1988 ..reminded me of that recent "congress" with "divine" post in this thread. That congress manifests in the western droit de seigneur which is interesting because of: First Knight And more interesting because of: After their travels in Scotland in 1773, Samuel Johnson and James Boswell documented the custom of the payment of merchet, linking it with the "right of first night". They paralleled it with that custom of Borough English, suggesting that the English custom favored the youngest son because the paternity of the eldest son was doubtful. which leads us to: Ultimogeniture, also known as postremogeniture or junior right, is the tradition of inheritance by the last-born of a privileged position in a parent's wealth or office. The tradition has been far rarer historically than primogeniture (sole inheritance by the first-born) or partible inheritance (division of the estate among the children) This is why Terry Pratchett's works should be read in schools for such elliptical, nevertheless, educating trail.
