Wine has been considered a divine drink since the Thracians. In Bulgarian folklore, many legends connect with her.
One of the most famous legends tells that when Khan Krum captivates the heroes of the Avar Khangan, he is interested in the cause of such a great state being destroyed. The three main factors were drunkenness, lying, and theft. Khan Krum has taken tough measures to overcome these vices. All vineyards were uprooted, and everyone who was caught drinking wine was punished with a stake.
The poor widow, named Elijah, had to raise her child in great destitution. But in her yard she grew a vine that gave her valuable fruit. According to the Khan's order, the vine had to be eradicated. The widow, however, decided to keep the last fruits and hide them in a pound to the hearth to feed her son.
Within months, the widow found that she had done wine without a wish. The next winter was very heavy, starvation and sickness tortured the people, but Elias was not afraid of the cold because she gave her son of healing wine. Han Krum had lions, and every night he let them go for a walk. One morning, however, one of the lions was found killed. People were very worried about the Han's penalties that would follow. The inn promised that whoever admits that he has committed the murder will be richly rewarded. But there was another condition - the daredevil had to be able to pull a hair from Khan Krum's beard.
Excited by the award, several henchmen went to the palace but were punished for their lie with 50 sticks. The poor widow's son Elias also went to the palace. To amaze everyone, he was able to pull a hair from Khan Krum's beard. The boy explained that the miraculous drink was the reason for his extraordinary power and courage. The inn asked the boy about his name, which was Mavrud. When he realized that the vineyard had given such a courage to the boy, Khan Krum ordered that vines be planted again all over Bulgaria, and wine and grapes would be called Mavrud, in honor of the courage of the hero.
Another version of the same legend is about the lamia that used to be on the Bulgarian lands, but nobody managed to destroy it, except a hero called Mavrud. His power was also due to the vineyards with which his mother had been feeding him, and they were baptized in his name.
