As far I get it, the family of Hornes is from Belgia ... so 1441 this should be Burgund.

I remember dark to have read the name Baw in the biography of Charles the Bold.
The Feast of Pheasants 1454 (which might or should mean "10 years after 1441" in the presented texts) was called the greatest event of its kind ... likely greater than the contemporary Trionfi festivities in Italy, which developed around this time. The center of interest at this event were clearly "knightly matters" and the idea was to collect energies for a crusade against the Osmans for the just fallen Constantinople (1453). Likely it was the "right time" for the Hornes sisters and their "female knights" ideas.

Burgund had founded the Order of Golden Vlies in 1430 and a follow-up in 1441 by a female has some internal logic ... generally knight orders were not an Italian idea, but appeared much more often in France, Germany and Burgund.

But still it might be of interest to know some details about Catherine Baw .... and the political situation of 1441. France and England had negotiated then a peace and it was opportunity to value the honor of Jeanne d'Arc, which seems to have been difficult immediately after her death and execution, especially since the church seems to have had some responsibility in the matter ... one couldn't calculate then, that France and Charles VII. restored themselves with some glory then.
Charles of Orleans was released in 1440 and Burgund played a central role in this development after 25 years .... Catherine Baw's activity should have an actual concrete and personal relationship to this event.
We know, that Filippo Visconti had immediately contact to Charles of Burgund and that he did send him a Boethius manuscript ... written by a prisoner once long ago in Pavia (Filippo's "home-city"). The content of the text: Fortune and virtues, isn't it?
And the Cary-Yale likely had a Wheel of Fortune (cause the Breara had one) and more or less had definitely the full seven virtues.
This tells Wikipedia to Jeanne d'Arc:
"The renewed French confidence outlasted her own brief career. She refused to leave the field when she was wounded during an attempt to recapture Paris that autumn. Hampered by court intrigues, she led only minor companies from then onward and fell prisoner at a skirmish near Compiègne the following spring. A politically motivated trial convicted her of heresy. The English regent John of Lancaster, 1st Duke of Bedford had her burnt at the stake in Rouen. She had been the heroine of her country at the age of seventeen and died at just nineteen. Some twenty-four years later Pope Callixtus III reopened the case and a new finding overturned the original conviction."
"twenty-four years later" should be 1455 and near to the feast of pheasants and likely near to the activities of the Horne's sisters. "Hampered by court intrigues" should mean, that she was not immediately recognized as the great spirit even in France, to which she was developed with the time. Likely Christine Baws activity shows the begin of Jeanne d'Arcs restoration, which finally turned in a political acceptance by the church ... which was unavoidable, after France had won the 100-years-war in 1453.
We know, that Filippo Visconti was very interested in Jeanne d'Arc in 1429 (letter of the poet-diplomat Cartier) and that Filippo possibly was influenced by Cartier's poem ("the cruel beauty" in 1424), when he ordered the Michelino deck (likely 1424/25), which has as a theme another cruel beauty (Daphne).
Well ... and we know, that the actual interest in early Trionfi cards was "for the young girls, when they married". Bianca Maria married October 1441. Naturally it was of interest to show the young bride "modern female developments". So "female knights" and "female virtues".
Sic .... but should be of interest to know Catherine Baw really, at least with some more details.

gives details of he case Jeanne d'Arc.
"Her attitude was always fearless, and, upon 1 March, Joan boldly announced that "within seven years' space the English would have to forfeit a bigger prize than Orléans." In point of fact Paris was lost to Henry VI on 12 November, 1437 -- six years and eight months afterwards."
Burgund did play itself a "bad role" in the year 1431. Bur after Jeanne d'Arc's prophesy was "proven" in 1437 and political reality did overcome earlier positions ... it seems, it was time to form a new pseudo-reality with a "good Jeanne d'Arc" ... so 1441 Christine Baw and her female knights.
