What Ireneusz means
Where Ireneusz comes from and what it has meant to the people who carry it.
Ireneusz begins in Greek, in the word eirēnē, meaning peace. The Greeks gave that name to a goddess of peace, Eirene, counted among the three Horai. From the same root the name reads as peaceful, one who brings peace. Its best documented early bearer is Saint Irenaeus of Lyon, a bishop and theologian of the second century who wrote a long Greek work against heresies. His feast falls on 28 June.
In Poland the name grew its own family of forms. Irena is the woman's version. Irek is what friends reach for on an ordinary day. On a school register the full Ireneusz stands in the column, while in the corridor the boy answers to Irek.
The imieniny sit in late June, near the summer. The sense has stayed legible for a long time, from the Greek word for peace down to the Polish gloss, niosący pokój.
