Simplify the following text for a Grade 10 native English-speaking person.
Original: The Sibylline Books should not be confused with the so-called Sibylline Oracles , twelve books of prophesies thought to be of Judaeo-Christian origin .
Simplified: The Sibylline Books were still to be found in the Temple of Apollo at Rome at this time , so it is thought possible that at least some of these Sibylline Oracles were partly the same .
