Kaganapan is one of Napoleon Abueva's work of art. Sculpted out of marble in 1952 when Abueva was still a young student at the University of the Philippines, this sculpture won the grand prize in the Arts Association of the Philippines' annual competition. With a dimension of 91.44 cms., Kaganapan literally interprets the female reproductive function as a fulfillment to women. It is now included in Abueva's collection.
