Peruvian playwright, Pedro de Peralta Barnuevo wrote four known loas for royal festivals in Peru and became well known by the 18th century. The sometimes criticism of artificial praise that comes from the form of the loa is especially evident with these royal feast performances. In particular, de Peralta Barnuevo’s loa for his play "Triunfos de amor y poder" "(Triumphs of love and power)" which was commissioned by Don Diego Ladrón de Guevara, the Bishop of Quito and Viceroy of Peru uses characters of Apollo, Neptune, the winds, muses, nymphs, land, air, and sea to praise the Spanish King Philip V and Guevara himself.
