[1] João Antunes was born in Braga, in the province of Minho, and, presumably, received some sort of education while restoring the Ribeira Palace during the Philippine Dynasty.
His main work is the Church of Santa Engrácia (started 1682) in Lisbon, a Greek cross building with curved façades typical of the Baroque architecture of Borromini.
This floorplan scheme, possibly derived from designs by Guarino Guarini, would greatly influence other churches in Portugal and colonial Brazil.
All of these churches were decorated with marble panels of Italian influence, anticipating the dominant role that Roman art would have in the Portuguese court during the 18th century.
The tomb consists of a large central chest with cherubs supporting the royal arms at the top.
