The Cult
Midir's cult, such as it was, is the cult of the síd itself. No inscription invokes him and no temple stood to him — Irish gods generally left literature, not dedications — but his mythic residence is a real, named sanctuary: Brí Léith, the hill by Ardagh in County Longford, which the Dindsenchas tradition glosses as his dwelling, the mound that opens as a court of crystal and silver. Within the mythological frame the síd-mounds are the Otherworld's halls, and Midir rules one of the greatest: the Wooing of Étaíne and the Taking of the Síd make him host at Brí Léith, and the young god Óengus is fostered in his house. If anything like devotion attached to him in the medieval imagination, it attached there — to the mound and its wonders — not to any rite we can recover.
