Knossos \'na-s3s\ Ancient royal city, Crete. It was King Minos’s capi¬ tal and the centre of the Minoan civilization. Settled by migrants from Asia Minor in the 7th millennium bc, it gave rise to a sophisticated Bronze Age culture. Two great palaces were built in the Middle Minoan period, the second c. 1720 bc after an earthquake leveled the city. About 1580 bc Minoan culture began to extend to mainland Greece, where it greatly influenced the Mycenaean culture. After its palace was destroyed by fire c. 1400 bc, it was reduced to town status, and Aegean political focus shifted to Mycenae. Knossos was the site of the legendary labyrinth of Daedalus.

have existed from the time humans first used vines and cordlike fibers to bind stone heads to wood in primitive axes, and were also used in the making of nets and traps. Knot making became sophisticated when it began to be used in the ropes, or rigging, that controlled the sails of early sailing vessels, and thus became the province of sailors. Knots are still depended on by campers and hikers, mountaineers, fishermen, and weav¬ ers, among others.

knot theory Mathematical theory of closed curves in three- dimensional space. The number of times and the manner in which a curve crosses itself distinguish different knots. The fewest possible crossings is three, for the overhand (trefoil) knot, which occurs in two mirror versions according to the directions in which the curve crosses itself. Knot theory has been used to understand both atomic and molecular structures (pro¬ tein folding).

Know-Nothing Party or American Party U.S. political party of the 1850s. The party’s precursor organization, the secret Order of the Star-Spangled Banner, was formed in New York City in 1849 from the anti-immigrant and anti-Roman Catholic movement, and lodges were soon established in other major cities. Members were instructed to reply to queries about their group with “I know nothing.” As its membership and importance grew in the 1850s, the group slowly shed its clandestine character and took the official name American Party. The party called for restrictions on immigration and on naturalized citizenship. Many local and state candidates won offices in the 1852 election, and by 1855 there were 43 Know-Nothing members of Congress. At its 1856 convention the party split over the slavery issue; proslavery advocates left to join the Demo¬ crats and antislavery adherents joined the Republicans. By 1859 the par¬ ty’s influence was limited to the border states.

With the accession of the Catholic Mary I, he fled to the Con¬ tinent. He served as pastor at Frank¬ furt am Main and Geneva until his return to Scotland in 1559.
