St Hyacinth (1185-1257) was a Dominican from Poland.
Educated in Paris and Bologna, he started out as a secular priest, but while in Rome he witnessed a miracle performed by Saint Dominic, and thereafter received the habit from him.
"One of his miracles is connected with a Mongol attack on a monastery in Kiev. Hyacinth was about to save a monstrance (or possibly a ciborium, it is unknown exactly which one) containing the Blessed Sacrament when he heard the voice of the Blessed Virgin Mary asking him to take her too. So he decided to take also the statue of the Holy Virgin. Despite the fact that it weighed far more than he could normally lift, it became miraculously weightless. Thus he saved both the Blessed Sacrament and the statue of Our Lady."
