Meskel, the Ge'ez word for a cross, begins with this letter, and it names one of the great feasts of the Ethiopian and Eritrean church year. The feast commemorates the finding of the True Cross and is kept in September with the building and burning of a tall conical bonfire, the demera, around which the clergy process in vestments while the singing goes on into the night. It is one of the moments when the whole apparatus this script serves becomes visible at once: the chant, the processional crosses, the ceremonial umbrellas, the drums and the sistra.
The cross is also the most reproduced form in Ethiopian religious art. Hand crosses, processional crosses and neck crosses are worked in openwork patterns that vary by region and by workshop, and a cross made at Lalibela and one made at Gondar are not interchangeable objects.
The same letter opens mashaf, the word for a book or a written volume, which is the other thing the script exists to serve. Between the cross and the book a Ge'ez sentence can name most of what an Ethiopian church physically contains, and the letter that begins both words is the fourth one a child meets in the recitation of the grid.
The word also gives a name. Mesqel stands in personal names of the kind Ethiopian naming favours, where a noun in the construct state is followed by a sacred term, so a form meaning the servant of the Cross is an ordinary name to meet and has been borne by kings. The vocabulary of the feasts and the vocabulary of ordinary naming are not separate things here.
