In 1953 he fell ill with pleurisy and was confined in Courel, where he remained until 1962, except for brief trips to Santiago, Lugo or Madrid.

This is a collection of poems that begins a poetic cycle in which he would keep working for many years, with new additions (Os Eidos II, 1974) and modifications.

Os Eidos confirmed Novoneyra's status as a poet, getting positive reviews by the likes of Otero Pedrayo, Isidoro Millán González-Pardo, Ánxel Fole, Borobó or Xosé Luís Franco Grande.

Novoneyra returned to Madrid In 1962, where he hosted radio and television programs on international, Spanish and Galician poets.

He attended Café Gijón literary gathering, where he met the members of the Galicianist group Brais Pinto, being the painter Reimundo Patiño among them.

Novoneyra married Elba Rey (a nurse who had taken care of the poet's sick mother at the end of her life) on January 5, 1973.

In 1988 the San Sebastian poet Koldo Izaguirre published a bilingual edition in Basque and Galician under the title Bazterrak / Os Eidos, I and II.

In 1979 he published Poemas caligráficos in collaboration with Xosé Manuel Pereiro and Reimundo Patiño, who provided the prologue.

The previous year he had been elected president of the Galician Language Writers Association, a position he held until his death.

In 1984, Xosé Luís Méndez Ferrín published De Pondal a Novoneyra, a book of literary criticism that explores the work of these two most outstanding Galician poets.

Finally, in 1999, already ill, he published Arrodeos e desvíos do Camiño de Santiago e outras rotas, with photographs by Federico García Cabezón and some calligraphic texts by the author.

On January 14, 2022, following his last will and testamente, his remains were transferred from Lugo to his house in Parada do Courel, now a museum in his memory.

In his poetry, Novoneyra makes explicit its nationalist and Marxist commitment, without ever ceasing to worry about poetic form and language.

Formally, he sought the best visual and sound results for the texts (using for this purpose various resources such as phonosymbolism, the use of dialectalisms, silences, or graphic symbolism).

It is not easy to systematize Uxío Novoneyra's work, since the same poems are frequently published, with more or less relevant modifications, in different books.
