Gaffiot’s massive Latin-French dictionary online; plus Du Cange’s medieval Latin glossary

A kind correspondent wrote today to supply some obscure words in the ancient catalogue of the Regions of Rome (and their monuments) attached to the Chronography of 354.  In the process I learned that a couple of really important dictionaries for Latin have come online in searchable form.

The first of these is Felix Gaffiot’s Dictionnaire Illustré Latin-Français of 1934, which was quite unknown to me despite its importance.  Various versions are online, as the Wikipedia article indicates – there is also a downloadable PDF -, but I used this one.  Gaffiot is good for very obscure words that other dictionaries do not include.  This had entries on such obscurities as “cochlis“, meaning a stair inside a column.

The second of these is Du Cange’s Glossarium mediae et infimae latinitatis, 1883-7, online here.  This is for medieval Latin.

I shall add both as links on the right-hand side in just a moment!
