Basilica of Saint Mary of the Angels and Martyrs
欧洲有一点名声的教堂大都有好几百年的历史。 有这么长久的历史,里面的典故少不了。 教会里也有过好人好事,不多而已。  看过的教堂一多了,自然腻味。
罗马的 Basilica of Saint Mary of the Angels and Martyrs 与众略有不同,有些意思。 它是米开兰基罗设计,监造的.

十八世纪初,教宗 Clement XI 要 Francesco Bianchini 在这个大教堂里设立一个测量子午线(经线,meridian line)的玩艺儿。 子午线是从地球的北极到南极
的虚构之线。 这个时候,教会已经不再认为一百多年前,伽利略对于天文的观察结论是 “反教会,反耶稣” 的了。 那个罪名,让伽利略在狱里受足了罪,差一点
就被虐杀了。

ZT: Bianchini's sundial was built along the meridian that crosses Rome, at longitude 12° 30' E. At solar noon, which varies according to the equation of time from
around 10:54 a.m. UTC in late October to 11.24 a.m. UTC in February (11:54 to 12:24 CET),[2] the sun shines through a small hole in the wall to cast its light on
this line each day. At the summer solstice, the sun appears highest, and its ray hits the meridian line at the point closest to the wall. At the winter solstice, the ray
crosses the line at the point furthest from the wall. At either equinox, the sun touches the line between the these two extremes. The longer the meridian line, the
more accurately the observer can calculate the length of the year. The meridian line built here is 45 meters long and is composed of bronze, enclosed in yellow-
white marble.

这个大教堂建筑在从前罗马的一个大澡堂子的废墟上面。 教堂的大门开在澡堂子的墙上。

 罗马各个儿教堂都有类似以下金璧辉煌的内观。
