The legend of the 365 children
From notes made by her widower, it is known that her death was unusual. Later, however, a legend was formed that she had died in childbirth after giving birth to no fewer than 365 children. An early form of this legend can be found in the 14th-century Tafel van Egmond, which can be found in the University Library of Utrecht. It briefly reports that she died after giving birth to 364 sons and daughters. The children did not survive. They were all buried together in Loosduinen, where an epitaph still exists.
Another 14th-century source is De Clerk's Kronyk van Holland. It gives a reason for the unusual multiple births. Margaret had on one occasion insulted a mother of twins with the assertion that these children would have to have two different fathers. As a punishment, she had been bewitched. The Kronyk mentions that 365 mouse-sized children were baptized in a large vessel and died afterwards.
Hermann Korner wrote his Chronica Novella between 1415 and 1535. Here, we find the legend in an embellished form. The mother of twins now has a name, Catherine, and is described as a personal enemy of Margaret, who is described as the wife of Count John of Holland. According to Korner, Margaret had said that it was just as impossible for Catherine to have two children at the same time from the same man, as it was impossible for Margaret herself to get as many children as there are days in the year. Simon, Catherine's husband, had thereupon rejected her and she was sent to prison, where she prayed passionately for her reputation to be cleared. Then Margaret had given birth to 364 children, and Simon had had second thoughts and re-acknowledged Catherine as his wife. The 364 children are described as tiny as crabs and as having died after baptism in a large vessel.
The story is also reported by Jan van Naaldwijk in his Croonijcke van Holland. In his version of the story, Herman of Henneberg was present at the birth and the baptism and he invited many nobles to act as godparents to his children. In this version of the story, the mother of the twins is a beggar. It has the additional details that the baptism was performed by Bishop Guido of Utrecht, and that all the boys were given the name of John, and all the girls were named Elizabeth.
In the 16th century, the legend spread more and more. Ludovico Guicciardini, who had probably visited Loosduinen, published a detailed account of what happened in 1567. Irenaeus in his book De Monstris, moved the event to the year 1555. Another writer relied on Jobus Fincelius when he gives the year of the miraculous birth as 1313 and stated Margaret was Irish.
In 1599, Cyriacus Spangenberg published his Hennebergische Chronica. It mentions 364 children, half of them boys baptized in the name of John, the other half girls who would be named Elizabeth. He refers to an inscription in the church in Loosduinen confirming the story. The copy of the Chronica that is preserved in Dresden has handwritten additional notes by the historian Nathaniel Carolus. According to these notes, some kind of monument for the deceased children existed in the church.
In the late 16th century, the theme was taken up by a Spanish song writer, who sang about the fate of madama Margarita and imputed her 360 children survived and their silver baptismal vessel was later exhibited in a church. The legend is also mentioned in Edward Grimeston's General History of the Netherlands of 1609, in Thomas Coryat's Crudities of 1611 and in John Stow's Annales. In 1620, the ballad the Lamenting Lady was printed in London; it probably used these sources. The theme also appears in William Strode's The Floating Island of 1639, in a poem by Robert Waring of 1651, in the works of Abraham Cowley, in Jacob Westerbaen's Ockenburgh of 1654 and in numerous other publications. The two versions with different numbers of children were often generously blended. Those writers who opt for the version with the 365 children were often curious about the gender of the 365th child, since it seemed to be clear that the genders had been evenly distributed. A clearly 17th century solution to this dilemma was to explain that the last child was a hermaphrodite.
The fascination of the crowds waned in the late 18th century and the legend came to be perceived as rather silly. Nevertheless travellers continued to visit Loosduinen.
