Researching on public culture or folklores is a measure to learn about the beliefs, traditions and myths of the people of old times and may be useful in self-cognition, self-confidence and eventually, identity achievement of the contemporary generation. A major part of society’s culture is represented in its oral literature. Therefore, such type of literature is extraordinarily along with the level of dreams, economy and beliefs of the public. Oral literature has unknown authors, but known narrators and in terms of contents, it includes perished or inaccessible dreams and expectations, myths, and individual and group beliefs of the people of the past, while some of these myths and beliefs are associated to supernatural creatures such as elf and fairy. When the mankind in the past failed to find a logical answer and in proportion to his/her knowledge, experience and expectations from his/her surrounding phenomena, (s)he was surprised and therefore started making imagination and fantasy and created supernatural and mythical creatures and attributing several issues to them, through which (s)he answered his realistic questions using fantasy responses and therefore mentally persuaded himself/herself. Khorasanian oral literature, which manifests these issues, has been sometimes in prose, and within the framework of stories and fictions, narrations, mazes, proverbs and sometimes as poems and been expressed in the form of masnavi, part, sonnets, couplets, quatrains, materia, etc. In this brief work, the author strives to study elf and fairy in poetic oral literature (lullaby, couplets, quatrains, etc.) of Khorasan. In other words, in this research article we are trying to find out that in which part of Khorasan poetic oral literature, elf and fairy are more manifested and emerged and how is the emergence of these creatures in different frameworks? Examining, studying and researching on public culture and oral literature are a measure to recognize the ancestors and take benefit from their minds and language for a better life.
