The fame of Giordano had already reached Madrid, when Don Cristobal de OntaÑon, a favorite courtier of Charles II., returning from Italy, full of admiration for Giordano and his works, so sounded his praises in the royal ear, that the King invited him to his court, paying the expense of his journey, and giving him a gratuity of 1500 ducats, and appointing him his principal painter, with a salary of 200 crowns a month.

The painter embarked from Naples on board one of the royal galleys, accompanied by his son Nicolo, a nephew named Baldassare Valente, and two scholars, Aniello Rossi and Matteo Pacelli, attended by three servants. Landing at Barcelona, and resting there a few days, he proceeded to Madrid, where he arrived in May 1692. Six of the royal coaches were sent to meet him on the road, and conduct him to the house of his friend OntaÑon. On the day of his arrival, by the desire of the King, he was carried to the Alcaza and presented to his Majesty. Charles received him with great kindness, inquired how he had borne the fatigues of his journey, and expressed his joy at finding him much younger in appearance than he had been taught to expect. The painter, with his usual courtly tact, replied, that the journey he had undertaken to enter the service of so great a monarch, had revived his youth, and that in the presence of his Majesty, he felt as if he were twenty again. "Then," said Charles smiling, "you are not too weary to pay a visit to my gallery," and led him through the noble halls of Philip II., rich with the finest pictures of Italy and Spain. It was probably on this occasion, that Giordano, passing before Velasquez's celebrated picture of the Infanta and her meniÑas, bestowed on it the well known name of the Theology of Painting. The King, who paid the painter the extraordinary honor to embrace him when first presented, gave him a still greater mark of his favor at parting, by kissing him on the forehead, and presenting him with the golden key as gentleman of the royal bed-chamber.
