The Plank That Wakes a Monastery

Monks on Mount Athos are woken for night prayer by another monk striking a board of wood. The board is the semantron (also spelled simandron), and a smaller metal one, the talanton, often hangs near the church door. Reference descriptions say a designated player gives three firm blows, walks around the church hitting the wood at uneven intervals, and finishes with three more. Wikipedia’s entry on the semantron names the candle-lighter as the one who sounds it at midnight, for the night offices that lead into Orthros, the service Western writers call Matins; I have not seen a monastery’s own account of its schedule.

A phone buzzes in one pocket, for one sleeper. A struck plank belongs to nobody and has no off switch. The man holding the mallet cannot be argued with either, because he is already up and already working.

What stays with me is the audience, and this part is my inference, not a sourced claim. Wood carries, so presumably most of the building hears the same blows at the same moment, and hearing them would mean two things at once: it is time, and everyone else just heard it too. The sound would then be a kind of proof that the others are awake, and a monk who rolls over does it knowing his neighbors are likely on their feet.

Other houses solved the same problem with other people. Saint Benedict’s Rule put a murmur from the next bed; the knocker-up sent a stranger down the street with a pole. The semantron is the cheapest of the three: one man, one board, the whole house.

Tradition ties the instrument to Noah building the ark, a legend that the same entry passes along without a source I could check. The wood itself is plain.

Three loose ends

What separates a semantron from a talanton?

Mostly a matter of material and size. The talanton is usually the metal one, and where a house has both, it is struck after the wooden board. Terminology varies, so check which word a given monastery uses.

Reference descriptions list three kinds: a hand-held plank, a large timber block hung on chains, and a smaller metal one, often horseshoe-shaped.

Does anyone still use one on Athos?

Yes. An AP photo caption shows Father Simon at Simonopetra calling monks and visitors to afternoon prayers with a mallet and plank. That is an afternoon service, not proof of the night routine.

Is Orthros the same as Matins?

Yes, Matins is the usual English name. Timing differs between monasteries, so a single Athos clock time would be a guess.
