Logical predication + Rhetorical construction

The challenge in this sentence lies in the correct placement of a prepositional phrase．In the original version，the placement of；n two letters to the historian Tacitus suggests that Vesuvius erupted in the letters themselves．Placing the phrase at the beginning of the sentence solves the problem．
