Tempera: see Webster, s. vv. “tempera” and “distemper”. {paint types} Alesso Baldovinetti: Florentine painter, b. 1422, or later, d. 1499; worked in mosaic, particularly as a restorer of old mosaics, besides painting; he made many experiments in both branches of art, and attempted to work fresco ‘al secco’, and varnish it so as to make it permanent, but in this he failed. His works were distinguished for extreme minuteness of detail. “In the church of the Annunziata in Florence, he executed an historical piece in fresco, but finished ‘a secco’, wherein he represented the Nativity of Christ, painted with such minuteness of care, that each separate straw in the roof of a cabin, figured therein, may be counted, and every knot in these straws distinguished.”--Vasari. His remaining works are much injured by scaling or the abrasion of the colors.
