as the viceroy triumphantly entered Oristano after having tamed the aforementioned 1478 rebellion, which threatened the revival of an Arborean identity which had been de jure abolished in 1420 but was still very much alive in popular memory. Thereafter, the ruling class in Sardinia proceeded to adopt Catalan as their primary language. The situation in Cagliari, a city subject to Aragonese repopulation and where, according to Giovanni Francesco Fara ( / ), for a time Catalan took over Sardinian as in Alghero, was emblematic, so much so as to later generate idioms such as ("he does not know Catalan") to indicate a person who could not express themselves "correctly". Alghero is still a Catalan-speaking enclave on Sardinia to this day. Nevertheless, the Sardinian language did not disappear from official use: the Catalan juridical tradition in the cities coexisted with that of the Sardinians, marked in 1421 by the Parliamentary extension of the Arborean to the feudal areas during the Reign of King Alfonso the Magnanimous, and Sardinian continued to be used in documents pertaining to administrative and ecclesiastical spheres until the late 17th century. Fara, in the same first modern monograph dedicated to Sardinia, reported the lively multilingualism in "one and the same people", because of immigration "by Spaniards and Italians" who came to the island to trade with the native Sardinians. The long-lasting war and the so-called Black Death had a devastating effect on the island, depopulating large parts of it. People from the neighbouring island of Corsica, which had been already Tuscanised, began to settle en masse in the northern Sardinian coast, leading to the birth of Sassarese and then Gallurese, two Italo-Dalmatian lects. Despite Catalan being widely spoken and written on the island at this time (leaving a lasting influence in Sardinian), there are written records of Sardinian, one of which is the 15th-century , written by Antòni Canu (1400–1476) and published in 1557. The 16th century is instead marked by a new literary revival of Sardinian, which was estimated to be the native people's ordinary language by the Jesuits in 1561. , by Hieronimu Araolla, was aimed at "glorifying and enriching Sardinian, our language" () as the Spanish, French and Italian poets had already done for their own languages ( and ). This way, Araolla is one of the first Sardinian authors to bind the language to a Sardinian nation, the existence of which is not
