The Ascension Bulls tradition belongs to San Juan Nonualco. It speaks of a character called Isidro Labrador. They tell that on Thursday of Ascension, the day that celebrates Christ's ascent to Heaven, Isidro began to work the field and when he arrived to the oxen, he heard one of them say: “Isidro, today we won't work”. He fell on his knees, begging forgiveness to God for not having remembered the date. Based on this event, the celebration is kept on Thursday of Ascension like the day dedicated to the bulls. In the six neighborhoods of San Juan Nonualco, the inhabitants manufacture a bull that they walk through the streets. The hermitages are adorned with altars and the Rosario is prayed. When concluding the prayer, the competition or fights of the bulls begin.
