PONCE, PR.- With the unveiling of The Battle of Treviño, by Puerto Rican painter Francisco Oller y Cestero (1833–1917), the Museo de Arte de Ponce celebrates the acquisition of a nineteenth-century masterpiece that has never before been exhibited publicly — a painting whose very existence, in fact, was unsuspected until just a few years ago. The work was part of a private collection that had been in the hands of a single family in Spain for over 130 years. “We are celebrating the arrival in Puerto Rico of The Battle of Treviño, a masterpiece by the island’s most talented and beloved nineteenth-century painter. It is a source of great pride for our institution that we are able to give both scholars and the public in general access to this important work, which now becomes a part of Puerto Rico’s artistic patrimony,” said Dr. Agustín Arteaga, director and chief executive officer of the Museo
