Hail Mary
In the Eastern Orthodox and Eastern Catholic Churches, the Hail Mary is very common.  It is said in the Greek form, or in translations from the Greek form.  The prayer is not said quite as often as in the West. However, it is well-known and is still used often.  It also appears in several canons of prayer.  It is usually sung three times at the end of Vespers during an All-Night Vigil.  It is also said many times during daily prayers.
