Johannes Rak of Sommerfeld, who was a Lusatian rhetorician and a celebrated poet, published a commentary on the grammar of Martianus Capella in which not only the different styles of the text both in Greek and Latin are explained, but there was also care on his behalf that many additions were made so that, being Capella obscure himself, he would not also be regarded as such due to scarcity of information. He would later write mainly about stress, partition, the origin of letters and vowel quantity and, in a rather extense manner, about the eight parts of the speech, in addition to the writing of Donatus on barbarism and solecism, which, in a similar way, appear briefly at the end of his book.
