De Humani Corporis Fabrica Libri Septem

Basel 1543 (Oporinus) is the true first, and there is no earlier or foreign-language precedent — Latin is the original language. Two adjacent books are regularly confused with it. First, the De humani corporis fabrica librorum Epitome (Basel: Oporinus, 1543) is a separate, simultaneously issued condensation with its own plates, not a part or extract of the Fabrica. Second, the 1555 Basel second edition is itself a collected book, carrying Vesalius's final textual revisions and superior presswork; it is a second edition, not a first, and must not be catalogued as one.
