Sorry, Danny, but I see there three mistakes:
1) Editions are a discrete process, not a continuous one. It is not a
flow *between* two dates.
2) The first edition, in 1482, is by Erhard Ratdolt of Venice all right;
but the second, in 1491, if it is quite the same as the first, is by
Leonard of Basel and Guillermo of Papia, still in Venice.
3) Campanus is what we would call now the *editor*, and gives some notes.
The translation is by Abelard of Bath (from an arabic manuscript).
