Other scholars hold that, after the poems were created in the eighth century, they continued to be orally transmitted with considerable revision until they were written down in the sixth century. After textualisation, the poems were each divided into 24 rhapsodes, today referred to as books, and labelled by the letters of the Greek alphabet. Most scholars attribute the book divisions to the Hellenistic scholars of Alexandria, in Egypt. Some trace the divisions back further to the Classical period. Very few credit Homer himself with the divisions.
