U radu se opisuje razdoblje Velikog tjedna u crkveno-pučkoj baštini Širokog Brijega. Veliki tjedan se smatra čvorištem crkvene i liturgijske godine. Vrijeme Velikog tjedna je ispunjeno trima krepostima, pokorom, postom i molitvom koji su ljudima pomagali u pripravi za nadolazeće vrijeme koje se veže uz muku i smrt Isusa Krista. U radu su navedeni suvremeni izvorni terenski zapisi molitvenih pjesama, običaja i vjerovanja koji su karakteristični za razdoblje od Cvjetne nedjelje do Velike subote. Posebna pozornost je posvećena svetom ili velikom trodnevlju, koje se izdiže bogatstvom pučko-crkvenih običaja. U znak na Isusovu posljednju večeru veže se običaj objedovanja zelja i običaj paljenja vatre na oranicama. Na Veliki petak bilježimo običaj pijenja crnog vina te izgovaranja molitvenih pjesama. Prema vjerovanju, molitvene pjesme koje su se molile na Veliki petak pripravljale su ljude na spasenje i ulazak u raj. Dani Velikog tjedna završavaju uskrsnim bdijenjem koje se događa u večeri Velike subote. Veliki dio navedenih običaja i vjerovanja prisutan je i danas u krajevima Zapadne Hercegovine, što govori o dubokoj religioznosti puka koja svjedoči koliki smisao religioznost pruža suvremenim ljudima., This paper describes a part of Lenten season. Special attention is devoted to Holy Week, which is considered to be the centre of the ecclesiastical and liturgical year. Holy Week is a time filed with three virtues: penance, fasting and prayer, which helped people to prepare for the upcoming time connected with the passion and death of Jesus. Its institutional purpose is heightened in the annual commemoration of Holy Week, marking the death, burial and resurrection of Jesus, which recalls the events from the Bible when Jesus was crucifid on Good Friday and which then culminates in the celebration on Easter Sunday. The paper presents some contemporary original fild notes of prayer songs, traditions and beliefs which are typical of the period from Palm Sunday to Holy Saturday. Special attention is given to the sacred or great Triduum, which highlights the richness of folk and religious customs. As a sign of Jesus’ Last Supper with the Apostles, which is described in the Canonical gospels there is a custom of dining cabbage and a tradition of lighting bonfies in the filds. On Good Friday, there was a custom of drinking red wine and saying prayer songs. According to belief, prayer songs which were said on Good Friday prepared people for salvation and entrance into heaven. Easter Vigil, also called the Paschal Vigil or Great Vigil of Easter, a service held in traditional Christian churches as the fist offiial celebration of the Resurrection of Jesus, is the day when Holy Week fiishes. Many of these practices and beliefs are also present today in Western Herzegovina, which speaks of the deep piety of the people and which demonstrates its meaning to modern man.
