This desire to promote the union could have been strengthened through the sudden death of Ludovico’s young wife Beatrice. Furthermore, this Sforza-Este device was surrounded by four painted plaques, adorning the central axis of each of the four supporting sides of the vault, each describing important events in the 1490s.

Ludovico solidified the alliance through the marriage of the duke’s niece Bianca Maria Sforza to Emperor Maximilian in 1494, a union described on one of the plaques. For more information, see Evelyn S. Welch, Art and Authority in Renaissance Milan (New Haven and London: Yale University Press, 1995), 233. Another plaque mentions the legitimate right of the Sforza to inherit the duchy after the death of Filippo Maria Visconti and describes the proclamation of this event by Maximilian in 1495. Kemp interestingly sug- gests that the Roman capitals on the inscriptions on the plaques may have been inspired by Luca Pacioli’s writings on the formation of Roman lettering in his De divina proportione (1497). See Martin Kemp, Leonardo da Vinci: The Marvellous Works of Nature and Man, rev. ed. (Oxford: Oxford University Press, 2006), 169. Yet another plaque has been defaced, leaving us only to speculate on its original contents, while a final plaque describes Ludovico’s 1495 victory against the French at the Battle of Fornovo. See Kemp, Marvellous Works (2006). Notably, all three remaining inscriptions bear reference to Ludovico’s new ally Maximilian I, perhaps not surprisingly as the Milanese defense against the quickly advancing French relied almost en- tirely on Sforza relations with the Habsburg emperor. Kemp has also pointed out that the motif of a tree with roots was one of Ludovico Sforza’s personal imprese, which represented strength and security due to the tree’s unfaltering presence even in adverse conditions. It was used twice in the roundels in the Piazza Ducale in Vigevano, but unfortunately their inscrip-.
