At that time the Sarmatians called the Mesians invaded Italy from the town of Larissa in Thessaly and captured many people as the spoils of war.

This seems to be somewhat corroborated by Ovid, book 3, Tristium Elegia 10, where he says of Sarmatia's lack of fertility at that time, "Aspiceres nudos, sineftonde, sine arbore campos, etc."

He also reports that the coat of arms was conferred at a time when the Sarmatians, irritated by the Romans' frequent raids, attacked Italy and captured several cities, leveling them, then plowing the land and sowing it with salt.

Finding the enemy asleep, he took away all their horses, after which Boleslaw attacked and easily conquered the horseless and still sleepy Bohemians.

The King therefore allowed Laryssa, as the progenitor of this clan was supposedly named, to bear on his shield the plowshares he had been carrying.
