Incensing the Gifts in the Roman rite:
LOL. Why I'm not suprised RCs have detailed explanation even for this.
I actually enjoy their diagrams for such things. That which was posted here--the incensing of the gifts--is similar to the way our priests incense the gifts during our Proskomide.
This is actually something for which I appreciate the Romans. We can poke fun at them for the complexity of their rubrics, but in their defence, I think they include everything in the rubrics. Romaios was just hinting at some of the specificity contained in the rubrics of the old Missal. In my experience, it's not so much that our Liturgies have less rubrics, but a lot more seems to be passed along through a kind of oral tradition.
For instance, when I was taught the liturgical rites, it was clear the rubrics in the priest's service book really only hinted at what to do. For example, the rubric might say "Then the priest censes the gifts", but you have to know how the priest censes the gifts at that particular moment. There's no Ritus Servandus
to refer to in case you forget how to do it. There are rules about how to hold your hands, how to elevate your arms, the proper way to ascend the step of the altar (including which foot to use first), how to turn towards the people for blessings vs. turning to distribute communion, etc. Knowledge of how to execute these rites is all passed down from teacher to disciple, and when you actually celebrate the Liturgy the first time, he's there to watch you, correct any errors, help when drawing a blank, etc. There isn't really any book to refer to, so you take good notes and practice, practice, practice. I suspect the Byzantine rite is similar in this, based on the rubrics class I audited, and I suspect this is the reason why even to this day Copts and Armenians send a newly ordained priest on a retreat to a monastery before he can serve the Liturgy publicly. There's a lot to learn if it's not all written down for you.
