What is "gagamba"

Gagamba (meaning “ spider”), subtitled The Spider Man, is a novel by award-winning and most widely translated Filipino author F. Sionil José. The novel is about a Filipino male cripple nicknamed “Gagamba”, a vendor of sweepstakes tickets in Ermita, Manila. After being buried in the wreckage, the seller survives an earthquake, together with two other fortunate characters, that occurred in the Philippines in the middle of July 1990. The novel simultaneously raised a “fundamental question” about the meaning of life and offers one “rational answer”.
