In addition to his figurative sculptures, Lobo also explored themes inspired by nature, often incorporating elements such as birds, flowers and animals into his compositions. These works, which are characterized by their organic forms and lyrical lines, illustrate his connection with nature.
The 1967 work "Oiseaux de mer" is a particularly fine example of Lobo's ability to breathe life and vitality into inanimate stone. The sculpture depicts a pair of intertwined seabirds, whose abstracted forms are characterized by a fluid dynamism and whose undulating curves convey a feeling of weightlessness.
In addition to their aesthetic appeal, the "Oiseaux de mer" also have a deeper symbolic meaning. As symbols of freedom, resilience and the untamed spirit of the sea, the seabirds are also metaphors for human experience.
Furthermore, "Oiseaux de mer" reflects Lobo's lifelong fascination with the interplay of form and space, and the negative spaces surrounding the sculpture convey a sense of rhythm and harmony.
