LONDON—Some standout young dealers are reinvigorating the Italian Old Masters market. The 32-year-old Fabrizio Moretti has expanded his business, which specializes in 14th- and 15th-century paintings, from its original Florence location to include—most recently—aspace on Manhattan’s Upper East Side, as well as a London outpost, on Bond Street. It’s at the latter site that he is staging a summer exhibition, July 7 through 18, featuring a newly rediscovered pair of panels by the Sienese painter Taddeo di Bartolo. Depicting Saints Francis and Simon, the panels, dated to around 1395, were originally part of a pentaptychaltarpiece in the Campigli and Sardi chapel of the San Franceso church, in Pisa, Italy,and have an asking price of $1 million. The works, with their rich, warm colors and flowing drapery softening the tight Gothic framing and composition, contrast with the more primitive, yet deeply tender, Nativity with Saint Gerome (€450,000; $704,000) by Pietro di Francesco Orioli(circa 1458–1496), another highlight of the show.

Also hosting a London exhibition this month—from July 2 through 12, in a temporary space at 8 Duke Street—are fellow Florentine gallerists Emanuele and Leonardo Piacenti, 27 and 24, respectively. The fratelli Piacenti are offering such gems as Gian Domenico Cerrini?s circa 1665 allegorical Truth Rewarded, showing a voluptuously bare-breasted blonde reaching out to a stern white-bearded man said torepresent recompense, and the Baroque painter Mattia Preti?s portrait Pindaro, circa 1630, in which the Greek poet’s deepset dark eyes stare alluringlyat the viewer.
