Osterrath is the family name of a stained glass workshop operating from Tilff, Belgium beginning in the final part of the 19th century. Their works were in the neo-gothic style of the period and samples or their works can be seen in cathedrals in Liège, Belgium and in many religious constructions in surrounding cities in Europe. Stained glass panels meant for religious buildings were sent as far as the United States and Canada.
Following World War II, the workshop eventually moved to Cowansville, Quebec, Canada and became one of the main suppliers of stained glass panels for churches being built in southern Quebec. Stained glass Panels produced by this workshop were sent to different cities and provinces in Canada such as Montreal, Hull and New Brunswick.
Pierre Osterrath followed on to become a renowned glass artist in Quebec and led in the creation of large stained glass panels on display in the Montreal metro system such as the ones found at the Berri-UQAM, Charlevoix, and Du Collège stations.
In peace there is nothing so becomes a man
As modest stillness and humility:
But when the blast of war blows in our ears,
Then imitate the action of the tiger;
Stiffen the sinews, summon up the blood
The gates of mercy shall be all shut up,
And the flesh'd soldier, tough and hard of heart,
In liberty of bloody hand shall range
With conscience wide as hell, mowing like grass
Your flesh - fair virgins and your flowering infants.
What is it then to me, if impious war,
Array'd in flames like to the prince of fiends,
Do with his smirch'd complexion, all fell feats
Enlink'd to waste and desolation?
What is it to me,
When you yourselves are cause,
If pure maidens fall into the hand
Of hot and forcing violation?
Your fathers taken by the silver beards,
And there most reverend heads dash'd to the walls;
Your naked infants spitted upon pikes,
