A short letter on an ostracon from Mons Claudianus in which Silvanus tells his brother Silvanus that he has reached the station of Xeron Pelagos, where he found the centurion Crispus and a certain Kelas. He mentions moving the stone piece called the Louter and asks his brother to keep a register of the workmen until he returns.
In English machine translation
Silvanus to Silvanus his brother, greetings. Know, brother, that we have arrived at Xeron Pelagos and found Crispus the centurion, and Kelas was still there, saying that we are bringing down the Louter.
So then, brother, you will write a register of the workmen until I come.
Farewell. Choiak 29.
The Louter ('basin') appears to be the name of a large quarried stone object being brought down from the quarry; Xeron Pelagos was a station on the desert road. 'Brother' may be a form of address between colleagues rather than literal kinship.
