What Kacper means

Where Kacper comes from and what it has meant to the people who carry it.

Kacper is the Polish spelling of an old name that Greek passed westward, and its short meaning is treasurer, the keeper of the treasure. In Polish that comes out as skarbnik, strażnik skarbu. The variant Casper travels the same road.

For a long time the name belonged above all to one of the Three Kings, Kacper beside Melchior and Baltazar, the magi of the Christmas story. That link fixed its place in the calendar.

Every January 6 the imieniny falls on Trzech Króli, and in many Polish homes the initials K+M+B go up in chalk above the door. A boy named Kacper holds the first of those letters. The gift he was said to bring was gold. The old gloss, treasurer, sits well with a king who brought gold.
