 Passage 2:In 1543, Europeans reached Japan for the first time when a junk belonging to the Chinese wokou pirate lord Wang Zhi carrying Portuguese traders shipwrecked on Tanegashima. The Portuguese introduced the arquebus to the Japanese during this chance encounter, which gave the Japanese, undergoing the bloody Sengoku period at the time, a powerful weapon with which they conducted their internecine wars. The discovery of Japan was attractive to Portuguese merchants and missionaries alike, for it gave the merchants a new market to trade their goods, and the Jesuit missionaries eyed Japan for new converts into Christianity. The warlords of Kyushu vied to get the Portuguese carrack (called the black ship by the Japanese) into their harbours, since the ship also brought considerable wealth to their fiefdoms in addition to the guns.
 Passage 3:The original 1857 asylum building (now the Nowotny Building) is a two-story Italianate structure of rough limestone with red brick detailing. The main facade features five sets of paired windows with limestone sills framed in brick and topped with brick segmental arches. The corners are reinforced with brick quoins, and a wide first-story portico extends to both sides of the main entry. A brick cornice marks the roofline, above which the gray metal roof is punctuated by an octagonal Italianate dome. The building was designed and built by Abner H. Cook, an Austin architect who had recently designed the Texas Governor's Mansion.
