The Madonna in the Mouscron Chapel at Notre Dame is a marble.

I think we may assume that the Bruges Madonna is the piece which Michelangelo executed for the Mouscron brothers, and that Condivi was wrong in believing it to have been cast in bronze.

That the statue was sent some time after the order had been given, appears from the fact that Balducci consigned it to the heir of John and Alexander, "as being their property;" but it cannot be certain at what exact date it was begun and finished.
IX While Michelangelo was acquiring immediate celebrity and immortal fame by these three statues, so different in kind and hitherto unrivalled in artistic excellence, his family lived somewhat wretchedly at Florence.

Lodovico had lost his small post at the Customs after the expulsion of the Medici; and three sons, younger than the sculptor, were now growing up.

Buonarroto, born in 1477, had been put to the cloth-trade, and was serving under the Strozzi in their warehouse at the Porta Rossa.
