to study believes and stories(narratives) of ancient ethnics(communities). you have to change your font in Persian we don't use such strange font (that's more likely Arabic)

correct form is:برای عقاید و روایات اقوام قدیم مورد مطالعه قرار بدهم

This is work of a very famous Farsi writer . I am able to find meaning of all the words in ARYANPOOR Farsi english dictionary also. But the problem is I am unable to understand the complete meaning . I think there are some spelling mistakes from my side , as I am new to using Farsi keyboard . I will try to write it again using Pinglish . Thanks .

That is not in Persian.
