Final answer:
The quote 'What signifies the reading of strange books' relates to the complex nature of ancient texts used in religious rites and the challenges of interpreting them. It highlights enigmatic practices within Greek, Roman, and Egyptian cultures. Option a is correct.
Step-by-step explanation:
The quote "What signifies the reading of strange books" is not directly attributed to a specific historical figure but rather appears to be a thematic reflection on the mysterious and often inaccessible nature of certain ancient texts, particularly those used in religious or esoteric rituals.
This is evident from the context provided, which discusses the ritual use of books in Greek and Roman religion, the role of temple scribes known as hierogrammateis, and the composition and preservation of 'divine books' in Egyptian temple libraries and the House-of-Life.
These texts, often inscribed with unknown characters or in hieratic script, played a significant role in the initiation and religious practices of the time. The complexity and exclusivity of these writings underscore the difficulties inherent in fully understanding ancient worldviews and the intricacies involved in interpreting such texts throughout history.
