Marcelino Menéndez y Pelayo described him as an excellent lyric poet who would rank among the greatest in any nation and during the finest literary periods.

He studied in Madrid and Barcelona, where he met Antoni Rubió i Lluch and was a disciple of the writer Josep Lluís Pons i Gallarza.

The volume was well received by friends and benefactors, mainly by Antonio Rubió y Lluch, and by critics such as Juan Valera or Marcelino Menéndez y Pelayo.

The narrative recounts a story of sailors from Ancient Greece who were captured by the native Balearic slinger tribes of the island, and features one of Costa i Llobera's most famous characters, the legendary seeress Nuredduna.

The book is made of a total of sixteen poems or odes, which attempt to reproduce in the Catalan language the verse forms of Ancient Greek and Roman poetry.

The book was very well received in Catalonia,[11] and also by Spanish critics, such as Marcelino Menéndez y Pelayo, who praised again the poet's metric innovations and went so far as to describe his verses as "worthy of being among the best that are written in Spain today".

[12] From abroad, Frédéric Mistral, who had received the 1904 Nobel Prize in Literature, sent his compliments to Miquel Costa i Llobera in a letter written in Occitan, deeming his odes "melodious" and "worthy of the laurels of Tiber.”[13] The same year, he gave the inaugural address of the Barcelona Floral Games and participated in the International Congress of the Catalan Language.

Later in 1907, the author, accompanied by other Majorcans such as the poet Maria Antònia Salvà, began a pilgrimage through the Middle East, which ended in Palestine and the Holy Land.

Several schools in Spain bear the name of the poet: one in the Can Caralleu neighborhood of Barcelona,[15] another in Pollença,[16] another in the city center of Palma[17] and another in the municipality of Marratxí.

On 19 January 2023, Pope Francis promulgated the decree that recognized the "heroic virtues" of Costa i Llobera and declared him a Venerable Servant of God.
