All these indications point to a genuine product of Michelangelo's first Roman manner; and the position of the statue in a chapel ornamented by the Bruges family of Mouscron renders the attribution almost certain.
However, we have only two authentic records of the work among the documents at our disposal.

Condivi, describing the period of Michelangelo's residence in Florence (1501-1504), says: "He also cast in bronze a Madonna with the Infant Christ, which certain Flemish merchants of the house of Mouscron, a most noble family in their own land, bought for two hundred ducats, and sent to Flanders." A letter addressed under date August 4, 1506, by Giovanni Balducci in Rome to Michelangelo at Florence, proves that some statue which was destined for Flanders remained among the sculptor's property at Florence.
Balducci uses the feminine gender in writing about this work, which justifies us in thinking that it may have been a Madonna.

He says that he has found a trustworthy agent to convey it to Viareggio, and to ship it thence to Bruges, where it will be delivered into the hands of the heir of John and Alexander Mouscron and Co., "as being their property." This statue, in all probability, is the "Madonna in marble" about which Michelangelo wrote to his father from Rome on the 31st of January 1507, and which he begged his father to keep hidden in their dwelling.

It is difficult to reconcile Condivi's statement with Balducci's letter.

The former says that the Madonna bought by the Mouscron family was cast in bronze at Florence.
