Of M.’s works, amid so many external influences, what stand out are the incisiveness of his style, the sharply defined forms, the composition laid bare on the surface despite the intended perspectival effects in certain backgrounds, and above all the clear, enamel-like, and precious colouring. These characteristics are evident both in his pleasing Madonnas—refined examples of a dreamy and nostalgic world—among which, besides the altarpieces mentioned at Pienza and Siena, one may recall the Assumption in London, that in Grosseto, and the exquisite St Barbara in S. Domenico, Siena (1478)—and in his celebrated Massacres of the Innocents, angular arabesques of contorted faces and taut limbs, which M. depicted in the floor tiles of Siena Cathedral (1481) and repeated in several panels preserved in Siena (churches of S. Agostino, 1482, and of S. Maria dei Servi, 1491) and in Naples (Pinacoteca, 1488).
