Alonso de Castillo Solórzano (1584?, probably in Tordesillas, Valladolid – 1647?, probably in Palermo) was a Spanish novelist and playwright.
[1] While in the service of the Marquis de Villars, he issued his first work, Donaires del Parnaso (1624–1625), two volumes of humorous poems; his Tardes entretenidas (1625) and Jornadas alegres (1626) proved that he was a novelist by vocation.
[2] He followed the Marquis de los Vélez in his disastrous campaign in Catalonia (the Reapers' War) and accompanied him to Rome, where the defeated general was sent as ambassador.
His prolonged absence from Madrid prevented him from writing as copiously for the stage as he would otherwise have done; but he was popular as a playwright both at home and abroad.
His Marqués del Cigarral and El Mayorazgo figurón are the sources respectively of Scarron's Don Jophet d'Arménie and L'Héritier ridicule.
