King John's love of poetry produced two Toledan poets, praised by Dr Pisa, Antonio de Heredia, a poet who "added rare glory to the Castillian muse" (probably an ancestor of the French academician, Jose Maria de Heredia) and a woman, Aloysia de Sigea, whose portrait may be seen in the Biblioteca provincial de Toledo. The fame of her erudition travelled to Portugal, and she is said to have written fluently in Latin, Greek, Hebrew, Syriac, and Arabian, though with so inconceivable a lack of decency that her muse to-day is not translateable in modern tongue. Doña Luisa Sigea of Toledo, and her witty daughter Doña Angela, were called "women philosophers," and their depraved works are supposed to be founded on the traditions of a mysterious association discovered under John II. at Sevilla, "a bizarre school whose immorality is understood by the terms of the law that prescribes it."[11] Alvaro de Luna found the Toledans no easy subjects to deal with. Pedro Sarmiento constituted himself chief of the revolution against the mighty Constable, and instead of a great lord the people had to do with a mean and avaricious hound. Don Alvaro appointed captains his sons, Pedro de Luna and Fernando de Rivadeneira, and ordered them to cross the river and besiege the town by the Puente de Alcantara. Sarmiento sent 50 horses and 500 foot out by the Puerta del Cambron under his son to surprise the Constable's forces near the river. A fierce battle ensued, and the King himself had to make conditions for the Constable with the violent and haughty citizens. Sarmiento demanded that the Constable should be given up or the King resign, and roundly accused his sovereign of weakness and favouritism. The King demurred, upon which Sarmiento invited his son to come and reign, but Henry soon found that he was only a tool in Sarmiento's hands, and left the city in dudgeon, to return speedily at the head of an army to crush the too powerful Sarmiento. Ordered to leave Toledo, Sarmiento loaded two hundred beasts with gold, silver, jewels, carpets, brocade, silk, and linen he had robbed of the citizens he oppressed, and to the prince's shame the impudent thief was permitted to carry off his treasure unmolested. The execution of the great Constable, infamously abandoned by his friend and sovereign, did not secure peace and content to rebel Toledo.
