Another son of Lorenzo was called Pietro, and, in conjunction with his brother, painted the Presentation, and Nuptials of Our Lady, in the hospital of Siena, on which the following inscription was legible: _Hoc opus fecit Petrus Laurentii et Ambrosius ejus frater, 1335_. The inscription is preserved by Cav. Pecci, who in 1720, when the painting was destroyed, transcribed it most opportunely for correcting Vasari, who had read _Petrus Laurati_ instead of _Laurentii_ in another inscription; from which he concluded this artist not to be the brother of Ambrogio; and from some similarity between his style and that of Giotto, had concluded that he was the disciple of the latter: but it is highly improbable that with such a father and such a brother, Pietro would have gone from home for instruction. Vasari gives, however, a most favourable opinion of this illustrious Sienese, which may suffice to vindicate his impartiality. He says of one of his pictures, "that it was executed with a better design and in a superior manner to any thing that Tuscany had then seen;" and in another place he asserts, that Pietro "became a better master than either Cimabue or Giotto." What could he have said further? might it have been asserted that he was, if not the disciple of Giotto, at least his fellow student in the school of F. Mino? (Vasari, tom. ii. p. 78. ed. Sen.) But granting that Giotto was not his master, how are we to believe him his fellow student? The first pictures of Giotto are traced to 1295; those of Pietro to 1327. And where, when, or to whom did F. Mino teach painting? Pietro's historical picture of the Fathers dell' Eremo remains in the Campo Santo of Pisa, where, in conformity with ecclesiastical history, he has painted the various discipline of those recluses. This picture, if I am not mistaken, is richer in ideas, more original, and better conceived than any one in that place. In the ducal gallery there is a copy of this picture, if not a duplicate by the artist himself: the taste of the colouring certainly belongs not to the Florentine, but to the Sienese school, of that period.
