High Middle Ages (13th century)
Feast: August 17
A Dominican who fled the Mongols carrying the Blessed Sacrament in one hand and a statue of Mary in the other — across a river.
The Mongols were burning Kyiv. Hyacinth ran to the chapel to rescue the Blessed Sacrament before the flames reached it. As he turned to leave, he heard a voice from the stone statue of the Virgin: 'Hyacinth, will you leave me behind?' The statue weighed as much as a man, but he picked it up — one tradition says it became light in his arms — and carried both the monstrance and the statue out of the burning city and across the Dnieper River. That is the legend, and Poles have loved it for eight hundred years. The historical Hyacinth was a Silesian nobleman who met Dominic de Guzman in Rome around 1220 and brought the Dominican order north into Poland, Bohemia, and the Baltic. He founded priories from Kraków to Gdansk, preaching in a region that was still partly pagan and about to be overrun by Mongol armies. He spent over thirty years crisscrossing northern Europe on foot, through forests and frozen rivers. He died in Kraków in 1257, on the feast of the Assumption — a date his friends considered no coincidence, given his devotion to Mary.
