[Romulus]

I think one could argue the following is a true epiclesis:

P. Veni, Sanctificator omnipotens aeterne Deus. et bene dic hoc sacrificum tuo sancto nomini praeparatum.

P. Come, O Sanctifier, Almighty and Eternal God, and bless, + this sacrifice prepared for the glory of Your holy Name.

[Catholicguy]

Excellent post, as usual.

[Tantumergo]

"P. Come, O Sanctifier, Almighty and Eternal God, and bless, + this sacrifice prepared for the glory of Your holy Name."

Which rite does that prayer come from?

In the Tridentine rite I would have thought that the following is clearly an epiclesis although the Holy Ghost is not explicitly invoked:

P: And do Thou, O God, vouchsafe in all respects to bless (+), consecrate (+), and approve (+) this our oblation, to perfect it and render it well-pleasing to Thyself, so that it may become for us the body (+) and blood (+) of Thy most beloved Son, Jesus Christ our Lord.
