Good point.
You might start a discussion about that on the lychgate Wikipedia article discussion page.
There might be an inconsistency in the description.

Selling them on the grey market to universities and medical schools for research and to perform educational obductions.
In England at the beginning of the 19th century there was an estimated need of 500-1000 corpses per year that could not be met by legal sources. Easy money…

l now also learned that the word “lych” is connected to the German word “Leiche”, just meaning “corpse”.
Makes sense, when you think about it…

A lychgate (from Old English līc, corpse) or resurrection gate[1] is a covered gateway found at the entrance to a traditional English or English-style churchyard.

In the Middle Ages, before mortuaries, and at a time when most people died at home, the dead were placed on a bier and taken to the lychgate where they remained, often attended against bodysnatchers, until the funeral service, which may have been a day or two later. The lychgate kept the rain off, and often had seats for the vigil watchers. Bodies at that time were buried in just shrouds rather than coffins. At the funeral, the priest conducted the first part of the service under the shelter of the lychgate.

Taken from Wikipedia

There’s a nice Wikipedia article about the bridges (they did it twice)

This doesn’t look like the Rhine, though.
It looks much too shallow and narrow.

Which makes the Roman bridge building even more impressive. There are large stretches of the Rhine that don’t even have bridges nowadays yet…
