full_context: Document 1: Hair jewellery: Hairwork, or jewelry made of human hair, has appeared throughout the history of craft work, particularly those made to be used for private worship or mourning. From the Middle Ages through the early twentieth century, memorial hair jewelry remained common. Hair, considered to be a remnant of the person it was cut from, also has often played a part in myths and legends; in a Swedish book of proverbs, one can read that “rings and bracelets of hair increase love” (Vadstena stads tankebok). One example can be found in Denmark, at Rosensborg’s palace, which is a bracelet of precious metal with a simple braided lock of hair - a gift from King Christian IV (1577-1648) to his queen. Another example would be the rings commemorating the execution of King Charles I of England (1600-1649), which circulated among his faithful supporters. Other famous people who owned hair jewellery include Napoleon, Admiral Nelson, Queen Victoria and her large family, Christina Nilsson and Jenny Lind.

Document 5: Museum of the City of Mexico: The Museum of the City of Mexico (Museo de la Ciudad de Mexico) is located at Pino Suarez 30, a few blocks south of the Zocalo, on what was the Iztapalapa Causeway, near where Hernán Cortés and Moctezuma II met for the first time. This building used to be the palace of the Counts of Santiago de Calimaya, who were the descendents of one of the conquistadors with Cortés. The house was extensively remodeled to much the appearance that it has today and remained in the family until 1960, when the Mexico City government acquired it from them in order to found the Museum that is found there today. The museum contains a number of elements of the old palace as well as 26 rooms dedicated to the history and development of Mexico City from Aztec times to the present. It also contains a library and the studios of painter Joaquín Clausell, who lived here in the late 19th and early 20th centuries.
Document 6: K'inich Yax K'uk' Mo': K'inich Yax K'uk' Mo' (] "Great Sun, Quetzal Macaw the First", ruled 426 – c. 437) is named in Maya inscriptions as the founder and first ruler, "k'ul ajaw" (also rendered "k'ul ahau" and "k'ul ahaw" - meaning holy lord), of the pre-Columbian Maya civilization polity centered at Copán, a major Maya site located in the southeastern Maya lowlands region in present-day Honduras. The motifs associated with his depiction on Copán monuments have a distinct resemblance to imagery associated with the height of the Classic-era center of Teotihuacan in the distant northern central Mexican region, and have been interpreted as intending to suggest his origins and association with that prestigious civilization. One of the most commonly cited motifs for this interpretation is the "goggle-eyed" headdress with which Yax K'uk' Mo' is commonly depicted, seemingly an invocation of the northern central Mexican rain deity known as Tlaloc to later peoples such as the Aztecs. However, modern strontium isotope analysis of the human remains recovered from the tomb attributed to him indicate that K'inich Yax K'uk' Mo' spent his formative years much closer to Copán, at Tikal, and had not himself lived at Teotihuacan.
