Saints often appear as characters in Croatian Latin school drama (which is mostly Jesuit). Here is how we index them in our digital bibliography. (A more technical note here.)
St Marianus, hermit and confessor of Berry, has until now received no identifier on the internet (though Fr Labbé wrote a page on him, available as a digital facsimile on BSB). Therefore his record has a digital ID / URL base exclusively in CroALa:
On the other hand, St Margaret of Cortona is in Wikipedia, so we can use her Wikidata URL: www.wikidata.org/wiki/Q254632.
