In the subsequent discussions in Spain respecting the government, Arriaza took part with those who advocated the rights of the absolute king. For this advocacy, on the return of Ferdinand VII. to full power, he received his reward, having been appointed Knight of the Order of Charles III., and Secretary of Decrees, besides receiving several other minor favours and offices. Henceforth Arriaza seems to have passed his life at court, in the quiet enjoyment of literary pursuits. He might be considered the Poet Laureate of Spain, as he seems to have allowed scarcely any opportunity to pass by unhonoured, of paying homage to the court in celebration of birthdays and other such occasions. His works abound with these loyal effusions, though they might generally have been better omitted. It must, however, be said, in justice, that he was evidently sincere in those principles, to which he adhered under all circumstances, even when the Constitutionalists were in the ascendent. Once only he was betrayed into an eulogium of the other line of opinions, which had an effect rather ludicrous, so far as he was concerned in it. In 1820, when the constitution of 1812 had been anew promulgated, a friend of his, Don Luis de Onis, was appointed minister from Spain to Naples, and a banquet having been given him on his departure, Arriaza was induced to write verses on the occasion, which, full of apparent enthusiasm, abounded in spirit and beautiful images, beyond his usual facility and fulness of expression. Carried away, no doubt, by the contagion of the company, he gave way to what, in soberer mood, he would have thought most dangerous doctrines. He painted the envoy as going “to Parthenope to announce our revolution;” adding, “To Parthenope that is now groaning beneath flowery chains, and to whom, though her syrens celebrate her in songs of slavery, thou wilt be the Spanish Tyrtæus, and raise them to the high employ to sing of country and virtue;” praising the heroism of Riego as to be offered as an example, “to throw down the holds of oppression.” The Neapolitan government obtained notice of this composition, and actually used it as sufficient cause for objecting to receive Don Luis as Spanish minister, “because he was coming to inculcate revolutionary principles.” Arriaza heard with horror that he was stigmatized as a liberal, and was urgent to disclaim such opinions, notwithstanding what he had written. Don Luis meanwhile was detained at Rome, until, by a strange coincidence, the revolution broke out at Naples also, and he entered the city almost as in fulfilment of the prophecy, that he was to be the harbinger of it.
