Sidapa is the Visayan god of death, remembered as the power who governs the length of mortal life. He is said to dwell upon Madia-as, the sacred mountain of Panay, where a great tree stands; at the birth of every person Sidapa marks upon that tree the measure of the coming life, and when a mortal attains the height set for him he must die. As lord of the appointed end he presides over the departure of souls toward the afterworld, which other deities of the sea and the underworld receive. A later and largely modern popular tradition pairs Sidapa with the moon Bulan in a romance; the attested older figure is simply the measurer and master of death.
