The writing on the αντίδωρον

Can anyone tell me the texts that are written on the αντίδωρον; On Sunday I received a piece on which was written in beautifully scripted Greek a word that seems to have been a word like επτηρούγ(χ?)α with a squiggle after the γ(χ?) which to me was indecipherable. Quite clearly no such word exists but i have given perhaps sufficient to ring a bell in someone's mind.

I think it depends on the part that you get: http://www.galilea.gr/vdata/Image/leitourgia.jpg

Αντίδωρο is a piece from πρόσφορο, the specially prepared bread. See here for an e-book on the subject.

The πρόσφορο is stamped with a wooden stamp carrying the ΙΣ ΧΣ (IC XC) ΝΙ ΚΑ logo. Here are pictures of this bread.

Since this has clearly nothing to do with the ΙΣ ΧΣ ΝΙ ΚΑ logo, could it be ευλογία; This is also used a synonym for the αντίδωρο (see above pdf, p. 20).

Please have a look at prosphoron. The writing on it can be customised.

I have an extra question, Theseus. How big was this αντίδωρο you received to have room for a ten-letter word on it?
