Santiago Manuel de Alday y Aspée

He also condemned the game known as palín or chueca, a form of field hockey of Mapuche origin, as well as the thick winter clothes worn by some clerics during cold weather, and the use of the sacramental bread by some people as a sealing wax on letters.

Alday, in a famous pastoral letter about women's fashions, ordered in 1782 that "...all women of whatever station or class extend the length of their clothes, employing round petticoats or half circle shaped skirts both inside and outside of their homes in a manner that reaches their ankles… and also, in the same manner, that women cover their arms up to the mid-point between the elbow and the wrist every time they leave the home or when they receive visitors at their home."

He founded San Lázaro (1775) in the suburbs of Santiago, and parishes in more distant areas, such as Paredones (1765), Combarbalá (1757), Pelarco (1787) and Renca (1764).

He organized a diocesan synod in 1763, hoping to enact clerical reforms and discuss the immoral customs of his flock.

He possessed one of the largest libraries in Chile during the colonial era of 2,058 volumes, which today is conserved in the Museum of Carmen de Maipú.
