The Israeli self-narrative during this period was one which largely erased the Palestinian presence on the land of historic Palestine prior to Zionist migrations of the early 20th century.
It was a period in which there was a heavy emphasis on inaccurate tropes, such as the idea that modern Jewish settlers in the region had encountered a barren and sparsely populated land; that they had made the desert bloom.
THE SYMBOL AS RESISTANCE
Besides the olive tree, Mansour's work features a number of other symbols that are associated with the Palestinian struggle, such as the Jaffa orange, thobes embroidered in the traditional tatreez style, the dove and the keffiyeh scarf.
"When I paint orange trees I am painting land that was occupied in 1948, and when I paint olive trees, I am painting about land that was occupied in 1967," he says referring to the Nakba, as well as the later Israeli conquest of the West Bank, East Jerusalem and Gaza.
Another more recent symbol, according to Mansour, is the cactus plant, which he says has become associated with Palestinian resistance and struggle.
THE PALESTINIAN ARTIST
Over the decades, Mansour has amassed a dedicated following and gained international recognition for his work.
He was awarded the 2019 Unesco-Sharjah Prize for Arab Culture; he also received the grand prize at the Cairo Biennial in 1998 and the Palestine Prize for Visual Arts in 1998.
Today Mansour dedicates his time to mentoring young artists and students, providing them with the opportunity to nurture their creative abilities and benefit from his lifetime's experience.
As an artist, Mansour says he would rather steer clear of politics. But as a Palestinian, art is a way out; a way to appease a conscience that will not allow him to look away from the fact of occupation.
