It was given that name because it was in a hilly area which was similar to the seven hills of ancient Rome in Italy. 它因与意大利的罗马有相似的丘陵地形而得名。
We know it is because in17:9,18 he talks about this city being on seven hills, referring to the famous Seven Hills of Rome. 之所以这样说,是因为在第17章第9节8,作者写道这个城市建在七座山上,指的是著名的罗马七丘。
