Portuguese family of wood-carvers. Manuel Abreu do Ó and his brother Sebastião Abreu do Ó (both fl Évora c. 1728–c. 1770) worked in collaboration, carving some of the finest and most influential Joanine and Rococo altarpieces in southern Portugal. They carved in delicate flat relief using patterns similar to those found in Spain, a style contrasting with the dramatic plastic effects seen in contemporary wood-carving in northern Portugal.
