It is also a significant source of the sublime. It comprises the use of appropriate words as well as metaphors and beautiful language. The use of appropriate and striking words is critical for establishing sublimity. According to Longinus, beautiful words are the very light of noble intellect. They strike us at first glance and remain in our memory forever. Longinus was a Greek writer and critic who lived in the 4th century BC. He is regarded as one of the most important critics in Western literature. In his work "On the Sublime", he discusses the nature of the sublime and offers some insights about how it can be achieved in art and poetry. He begins by defining the term "sublime" and then goes on to explain that it has two meanings: one negative and the other positive. He says the negative meaning relates to what we feel when faced with dangers, while the positive meaning concerns what inspires awe in us when viewing something great or powerful. He continues by explaining that the negative aspect of the sublime involves fear and danger, but also notes that it can have other aspects such as pain, grief, and loneliness. However, he states that these are not necessary components of the sublime but rather factors that occur naturally within certain situations.
