Advantages of Parallelism

I just read about advantages of parallelism in the book   The New Oxford Guide to Writing by Thomas S. Kane  and so I wanted to share the information especially because our class recently completed an assignment about parallelism.  According to Kane, parallel sentences are "rhythmic ."   When several verbs refer to one subject the focus is on the  action of the subject.   An  example written by Ralph Roeder, an American historian would be, "As the danger grew near, they would wheel about, toss their heads into the air and dive."  Additionally, according to Kane, parallelism facilitates understanding and reinforces meaning by presenting relationships between words.   For example  Bernard Shaw wrote,  "Joan of Arc, a village girl from Vosges, was born about 1412, burnt for heresy, witchcraft and sorcery in 1431; rehabilitated after a fashion in  1456, designated venerable in 1904; declared Blessed n 1908; and finally canonized in 1920."
