Born in Kinshasa (DRC) in 1992. He lives in Kinshasa.

He enrolled at ABA Kinshasa in 2012, but had to leave in 2013 to make ends meet. He was able to devote himself to art once again from 2015. Mondombo started out painting on canvas, but was not satisfied with the results. He then got hold of second-hand tarpaulins, salvaging them from markets and street sellers in Kinshasa. This medium gives his work a powerful symbolic dimension. It reflects the socioeconomic situation of the people of Kinshasa, and beyond that, the precariousness of the human condition.

Inspired by a science fiction film, he firstly created a series of half-abstract, half-realist allegorical motifs in which astronauts are depicted. Mondombo then turned his hand to portraits, mainly of women, painted with acrylics, to which he added stitching to symbolise repair. Then, in 2020, Catheris embarked upon a series called Notre histoire, exploring his country’s colonial past. These artworks bear witness. The simplified shapes, the figures primarily depicted as shadows on flat tints of pure colours, have a direct intention, and the end result is especially striking as the works are in a large format. The series was shown in Kinshasa in 2021 (at the Texaf-Bilembo cultural centre).

Catheris has been supported by Angalia since 2021, and is also represented in New York by the Ethan Cohen Gallery.
