Remark: in those old times it was customary in the Netherlands that the Dutch name was made Latin, especially for learned persons. Groningen was a famous centre of Renaissance science. Perhaps this Kemerer (Camerius) was part of it.

The first printed edition was made in 1535 with an accompanying Latin translation by the German classical scholar Joachim Camerarius. This was reprinted in 1553 and is "notable for offering the first Latin translation based upon a Greek rather than Arabic source".[125]:269 Robbins noted the page numbers of the 1553 edition in the Greek text which faces his English translation, stating "My collations have been made against Camerarius' second edition, because thus far this has been the standard text and it was most convenient".[133]
The book Tetrabiblos is about astrology.
