Question: When was the 17th Dynasty in Egyptian history? Passage:The Egyptian collection consists of about fifty itens, including some objects which stand out in the context of Brazilian museums, due to their quality and rarity. Since these objects are not related to official archeological excavations, their exact place of origin remains largely unknown. The collection includes a number of large pharaonic statuary, in which a head of a Pharaoh in a nemes headdress is the centerpiece. Among the funerary itens, there is a coffin mask with encrusted glass eyes dating back to the 17th Dynasty, and other pieces which reflect the importance of animals in Egyptian rituals, such as a coffin of a mummified cat from the Ptolemaic period. The collection also includes reliefs and fragments of architectural decoration, such as a prominent temple bas-relief of a goddess with the body of a woman and the head of a lioness, dating back to the 3rd Intermediate Period.
