Step-by-step explanation:
The masterpiece considered for embodying a unique style through the interrelationship of figures, exaggerated proportions, and the use of open space is the “Veranda post of enthroned king and senior wife (Opo Ogoga)” by Olowe of Ise (Yoruba peoples), dating from 1910-1914 C.E. This work is made of wood and pigment and is noted for its dynamic composition and expressive quality that captures Olowe of Ise's personal artistic vision and technical skill. The stature captures the interplay between figures, defining the space around them, and demonstrates an exaggerated form that is both a hallmark of the artist's style and a symbolic representation of power and prestige in Yoruba culture.
