Answer :
The complex monolog ballad was most famous amid the mid-eighteenth century, at the tallness of the neoclassical period. Neoclassical writing was composed in the vicinity of 1660 and 1798. This day and age is separated into three sections: the Restoration time frame, the Augustan period, and the Age of Johnson. Scholars of the Neoclassical period attempted to emulate the style of the Romans and Greeks
The type of poem that was the most popular during the mid-eighteenth century, at the height of the Neoclassical era was a heroic epic. So, the era is Neoclassicism, which means that it is a "New Classicism," when authors tried to imitate the art which was created during the Classical era. The most popular type of poems at that time were heroic epics, so if Neoclassicism finds inspiration in Classicism, obviously the most popular type of poem then is going to be the same thing.
