To judge from mu 131 (the cross-reference given) the headword phrase refers to a monumental sculpture in Constantinople. See further, next note.
1Adler reports that one ms (F = Laurentianus 55.1) reads *)amastri/si for *)amastrianoi=s. Be that as it may, for the Amastrians (of the S. Black Sea coast) see e.g. Strabo 12.3.1-10; Barrington Atlas map 86 grid C2. Their relevance here is because of the public square in Constantinople known as the Amastrianon/Amastrianum.↩
