José Juan de Dios Mateo Osbaldo Botaro Lepiani Toledo (20 September 1864, Lima – 28 November 1932, Rome) was a Peruvian painter.
He considered art to be his natural vocation, however, so he began studying with Francisco Masías [es] and Ramón Muñiz, a Spanish painter living in Lima, about whom little is known.
He eventually settled in Rome, where he lived a somewhat dissolute life and created few original works, preferring instead to copy the Old Masters, such as Raphael and Titian, and sell the reproductions to American tourists.
Among his works depicting the War of the Pacific, the best-known include the death of Colonel Francisco Bolognesi at the Battle of Arica, Alfonso Ugarte riding his horse over a cliff to prevent the Peruvian flag from being captured, and a scene from the Battle of Miraflores where weaponless civilians rise to the defense of Lima.
Although lesser known, he also created canvases related to the Spanish Conquest, the War of Independence and the coup d'état of 1895, led by Nicolás de Piérola.
