Context: Attention to calligraphy and the alphabet and the appearance of letters in Iranian-Islamic culture has occurred in various arts. In the art of calligraphy, calligraphers have been writing letters in the most beautiful form for a long time, and these beautiful forms reached the walls of mosques and holy places in addition to books. But in the world of mind and language, poets also thought about letters and alphabets and considered it a suitable and familiar platform for creating images of imagination. They have long used the letters of the alphabet to express their ideas, thoughts and intentions in illustrations.
Purpose: Based on this, in this research, it is assumed that the poets used the Persian alphabet as the basis for the creation of rhetorical images, and this category has also evolved, and with the change in the style of the poem, the way of creating arrays based on the alphabet has also changed. For this purpose, a number of poets from both Khorasani and Iraqi styles have been selected and verses containing the use of alphabet letters have been extracted and analyzed with the help of virtual space and insertion software.
Conclusion: This research shows that the letter "A" has been the most widely used letter in image creation with multiple and diverse meanings and concepts. Kufi is a symbol of bending.
Next to the letter A, other letters; including jim, dal, sin, lam, mim and non have been used more in creating themes than other alphabet letters. In terms of frequency, this fantasy method started with a low frequency in Rudaki's poetry and continued with the most use in Sanai's and Molvi's poems.
This research also shows that the poets of Iraqi style have created more images with alphabets in terms of frequency and in addition to simple and tangible images, they have also used them in symbolic forms and therefore they have created more different and deeper images.
