MARQUES PERDIGA0, Joao da Purificacao (mar-kes-per-de-gang'), Brazilian bishop, born in Vianna, Portugal, about the end of the 18th century" died in Pernambuco, 30 April, 1864. He received his early education from private tutors, and was graduated as D.D. at Coimbra in 1815. After being ordained priest he sailed for Brazil, arriving at Rio Janeiro in May, 1816. Immediately on landing in Brazil he was appointed rector of a parish in Pernambuco, where, besides conducting a school for the training of laboring men, he established drawing and other educational classes in the evenings and on Sundays, and was active in procuring work for the poor. His popularity as a preacher soon gained for him a position of great influence among the people of the province, who elected him representative to congress in 1826, but he positively declined. On 18 October, 1829, Pedro I. appointed him bishop of Pernambuco, and this choice was confirmed by the pope Leo XII. on 28 February, 1831. His thorough knowledge of the wants of the people enabled Marques to give valuable practical advice to the government, and to do much in behalf of the poorer class. In 1839 the civil war known as "Cabanos" desolated the province, but the exertions of Marques, who was esteemed by both sides, brought it to a peaceful end. In 1841 he went to Rio Janeiro to crown the emperor Pedro II., and in 1853 finished at his own expense the magnificent church-building of the "Carmo" in Pernambuco. The districts of Gloria, Olinda, Iguarassu, and Ooyana are indebted to Marques for many important charitable institutions and several schools.
