In the Middle Ages, monks were what is today the internet. They published, reproduced, kept and passed on vast amounts of data.
The monks' translations and transcriptions were hard work. Hard-working monks had to deal with a unique set of problems. Bookbinders used to join together the wrong pages, for example. To prevent this, scribes and authors repeated the last line on the new page.
Texts were long and brevity a virtue.Where it did not exist, it was created. Authors abbreviated words as short and common as "ad". "ad" is Latin for "at".
'@' seems like a logical abbreviation if you know that medieval fonts had a 'd' character that looked much like a mirrored 6.
