Breathings over internal rho 
"a double rho within a word is written with a smooth breathing over the first rho and a rough breathing over the second — ῤῥ"
In my own reading of ancient Greek texts I've never seen breathings over rhos within a word, e.g. ἔρραψα (Hdt. 9.17), nor have ever heard of such a convention. I don't want to remove it, if it actually holds for medieval manuscripts or something, but I'm dubious. Dd42 (talk) 23:14, 19 February 2008 (UTC)

Up to 2004-05-08, the page at Rho was the page about the letter. It was cut-and-paste-moved to Rho (letter), and Rho was turned into a disambiguation page. I have now divided and re-merged the edit histories, moving the history of the disambiguation page to Rho (disambiguation), and merging the more recent history of Rho (letter) back into Rho, per WP:PRIMARYTOPIC.
