HYACINTH (hī'a-sĭnth, Gr. hyakinthos). The name of a color in ASV (Rev.9.17; rsv “sapphire,” niv “dark blue,” kjv “jacinth”).

1185-1257. “Apostle of the North.” Nobly born Jacek Odrawaz (the former name was corrupted by a later writer), he studied at Cracow and probably Bologna. As a priest he entered the Order of Preachers at Rome in 1217/18. Having accompanied his uncle who was to be consecrated in Rome as bishop of Cracow, he is said to have witnessed St. Dominic's miracle of raising the dead. The earliest biography was written a century after Hyacinth's death by Stanislaus of Cracow. Later accounts are not reliable. Hyacinth had an important part in the extensive Dominican missionary efforts, having founded several houses of the order—e.g., at Cracow, Danzig, and Kiev-as well as making journeys of thousands of miles on foot to preach in Scandinavia, Lithuania, Bohemia, Greece, Russia, Tibet, and his native Poland. Miracles of crossing rivers dry-shod, restoring the blind, and raising the dead have been attributed to him. Hyacinth was canonized in 1594.

HYACINTH or jacinth (q.v.) is a gem variety of the mineral zircon (zirconium silicate). It is transparent and generally red in color, but may be orange or brownish. The term prob. was used by ancient writers to refer to a blue material, such as blue corundum (sapphire in the gem variety) or turquoise (cf. Rev 21:20 NEB). See Jacinth.

International Standard Bible Encyclopedia (1915)

the Revised Version (British and American) uses this word in Re 9:17 for the King James Version "jacinth," with reference, not to stone, but to dark-purple color. In Re 21:20, where stone is meant, the Revised Version (British and American) translations "sapphire."
