This term I am teaching a course on women in sixteenth century England. When planning it I thought that a good way in which to approach the topic would be through giving a series of tutorials on individual women and their lives, both as of interest in themselves and also as a means of exploring the wider context and implications.
My first choice was a joint study of those two great matriarchs of the earlier Tudor period, who were also formidable as women in their own right - Lady Margaret Beaufort and Margaret Pole, Countess of Salisbury.

Her friend and confessor Bishop Fisher, who preached her funeral sermon at her month’s mind, said of her “Every one that knew her loved her, and everything that she said or did became her.”
The ODNB biography of Lady Margaret is
here. The authors Michael Jones and Malcolm Underwood have written the standard biography
The King's Mother (Cambridge 1992) . There is also one on Wikipedia, with links,
here.
There is a website about her from the school she founded in Wimborne Minster
here; it is of particular interest in that it includes a useful
map of her estates, which gives an indication of her political and social influence. The Westminster Abbey website has an article concentrating on her tomb and funeral
here.

What struck me was how very similar the two ladies were in so many aspects of their upbringing and personality, and in many, but not all, of their lives. Most notably, of course, Lady Margaret died full of years and honours, the grandmother of the new King and esteemed as a benefactress, whereas Margaret Pole died particularly horribly at the hands of the headsman an attainted traitor - but in reality the victim of Henry VIII's vindictiveness.
Her violent end is a reminder of the extent to which both women lived all their lives in the shadow of violence. Thus Margaret Beaufort lost her uncle, two fathers-in-law, her step father, three male Beaufort cousins, their half brother and a cousin by marriage, two more cousins and finally a brother-in-law on the battlefield or scaffold between 1455 and 1495. Margaret Pole lost both grandfathers, a great uncle, father, two uncles, five cousins, her brother and her eldest son in similar fashions between 1460 and 1539, before she herself suffered in 1541.
Margaret Beaufort was, it was to turn out, more fortunate in the reign of Richard III when she had a son in exile who was a clear threat than was Margaret Pole in the time of Henry VIII when Cardinal Reginald Pole was perceived as one of the King's principal opponants, but out of reach on the continent.
Both were women who, in a certain sense, had to make their way in the world. Their fathers both died when they were young, and in adegree of dishonour, and Margaret Pole's mother the Duchess of Clarence had died when her daughter was three. Margaret Beaufort's mother lived until 1482, nearly long enough to see her grandson become King. Both women were of importance in the marriage market, and in both cases finding suitable husbands a political issue. Margaret of Clarence was married to Margaret Beaufort's nephew, as part of Henry VII's policy of marrying Yorkist female realtives to safe husbands linked to the new ruling branch of the royal house. Thus his mother's younger half-brother, John Viscount Welles, became his brother-in-law when he married one of Elizabeth of York's younger sisters, Cecily.
As landowners they are proof that aristocratic women (and those of fewer resources than these two exceptional figures) could and did manage great estates and exercise local influence. Under Henry VII Margaret Beaufort was a very substantial landholder and executive presence in the eastern counties. Both enjoyed exceptional status - Lady Margaret as the King's Mother and transmitter of his dynastic claim, signing herself "Margaret R", Margaret Pole, with her restored hereditary Salisbury title as one of only two women in the sixteenth century who did not have a titled husband - the other was the creation of Anne Boleyn as Marquess/Marchioness of Pembroke in 1532. In terms of income she ranked fifth amongst the peerage.
Both were devout women - examples of the aristocratic piety of the age, which included Cicely Duchess of York, grandmother of Countess Margaret, and later on Queen Catherine of Aragon and Queen Mary I. Both were patrons of the Church and learning. In John Fisher, as Lady Margaret's confessor and counsellor, and Reginald Pole, Countess Margaret's son, they had contact with two of the leading English churchmen of the age, both of whom were to become Cardinals.
As women of high birth they were seen as authoritative on precedence and ceremony in the case of Margaret Beaufort, whilst Margaret Pole was not only a lady-in-waiting to Queen Catherine, but chosen as governess to the Princess Mary when she was seen as heiress apparent in the 1520s.
Margaret Pole was beatified as a martyr in 1886, and it is perhaps surprising that no-one appears to have sought the beatification of Lady Margaret - being Henry VIII's grandmother should not be held against her. I strongly suspect that she would disapprove very strongly of his actions, and given the opportunity in the afterlife to tell him so would not hesitate so to do.

It is not clear when the Duke's effigy was commissioned. A time interval of more than thirty years after his death is a long time, even by fifteenth century standards. Looked at on its own, the male figure could be contemporary with the time of the Duke's death. But both hands couldn't be changed, and it was always intended to hold the image of someone who died later; in this case almost 40 years later. Duffy suggests that it is possible that the male effigy was carved 'in retrospect' using an old suit of armour, old effigy designs. To this the photographer responds that being carved in retrospect was very rare during the fifteenth century, and cannot cite any dated example.

At Framlingham in Suffolk the second and third wives of the fourth Duke of Norfolk lie with a gap between them - he, being beheaded in 1572, never got to join them, and the tomb is a rare example of one that has never been completed. Similarly, in a later age, when the effigy of Prince Albert was carved and installed in the Mausoleum at Frogmore after 1861 one was prepared for Queen Victoria, but not installed until after her death in 1901. When that occurred the effigy had been mislaid at Windsor and was found after a search walled up in the castle. So delay in installation ( or even loss of an effigy) is not inconceivable.
Carving an effigy in the dress of a generation earlier would, I think, be very unusual, although in the fourteenth century sculptors were, apparently, often a generation behind in what they carved - thus actual armour was more advanced than that depicted on effigies. This emerged at a conference I attended in 1993 on Yorkshire figures.
The tomb would have required several stages to assemble. The base is Purbeck marble, so local to the area, but the effigies are of alabaster which would presumablymean they originated in either the Derbyshire-Nottinghamshire area, or have been produced in London and transported to Wimborne.
The choice of the motif of the clasped right hands, chosen, it is clear when the Duke died, or at least his effigy commissioned, may only be a convention, but is, as is pointed out above, one associated with an earlier period - such as the Arundel tomb in Chichester Cathedral from the 1370s. Perhaps we should give the Duke and Duchess the benefit of the doubt and assume there was genuine affection which they wished to embody in stone.
