Eucharistic Adoration began when?

[Fraevo63]

I asked this in RCIA and the instructors didn’t know the answer:
When, in the history of the Church, did the practice of Eucharistic adoration begin? Thank you.

 

[Mary888]

The Last Supper.

 

[BartholomewB]

From Donald Attwater’s Catholic Dictionary, under Eucharistic Adoration (p. 178):

This was a development in the Western church of the 11th and subsequent centuries, which received the encouragement of the Church in the establishment of the feast of Corpus Christi (1264).
