90:11 A wall or a tablet which has on it drawings or portraits, and below them are captions (saying) ''this is a picture of so and so'' and ''this is a portrait of so and so'', it's forbidden to read this caption on Shabbat, and even to look at without reading is forbidden.1 Similarly, war novels and histories of Gentile kings, and similarly, books of secular parables and proverbs, such as the ''book of Emanuel''2 and certainly erotic writings, it's forbidden to read them on Shabbat.3 Even to look at them without reading out aloud, and even during the week is forbidden because of ''idle chatter'',4 even if they're written in Hebrew. On (reading) erotic writings there is a further prohibition that they arouse the ''evil inclination''5 itself. However, those history books from which one gets ethical lessons and the fear of G-d, such as the ''Book of Josephus'' and the like, even if not written in Hebrew, are allowed to be read even on Shabbat. Nevertheless, it's inappropriate to spend too much time on them.6

כותל או טבלא שיש בו איזה צורות או דיוקנאות וכתוב תחתיהן זו צורת פלוני וזו דיוקן פלוני אסור לקרות כתב זה בשבת ואפילו לעיין בו בלא קריאה אסור וכן ספרי מלחמות וספרי דברי הימים של מלכי העולם וכן מליצות ומשלים של שיחת חולין כגון ספר עמנואל ומכל שכן דברי חשק אסור לקרותן בשבת ואפילו לעיין בהם בלי קריאה בפיו ואף בחול אסור משום מושב לצים אפילו הם כתובים בלשון הקודש ובדברי חשק יש עוד איסור שמגרה היצר הרע בעצמו אבל אותן ספרי דברי הימים שיוצא מהם עניני מוסר ויראת שמים כגון ספר יוסיפון וכיוצא בו אפילו כתובים בלשון ''לעז'' מותר לקרותם אפילו בשבת ומכל מקום אין ראוי להרבות בהם
