XCIV. Trajan to Pliny
IF the petition of the Amiseni which you have transmitted to me, concerning the establishment of a charitable society, be agreeable to their own laws, which by the articles of alliance it is stipulated they shall enjoy, I shall not oppose it; especially if these contributions are employed, not for the purpose of riot and faction, but for the support of the indigent. In other cities, however, which are subject to our laws, I would have all assemblies of this nature prohibited.
