But Could Peter Write Anything?

1 and 2 Peter, other letters allegedly by him, a Gospel, three apocalypses. But Really? Could Peter even write? Today we take it for granted that an important and influential person can write. Not so for the ancient world. Would a fisherman from rural Galilee have been able to write well enough to compose whole texts? Elegantly phrased, not in his language? Could he have learned to write in later life? If in fact Peter couldn't write, then who composed the works attributed to him?
