About this Book Scan

Carefully scanned in full colour from our original printing purchased in the 2000s.

Manoah Sibly, brother to Ebenezer, published a two-volume edition of the first English translation of the text contents of famed Italian Renaissance astrologer Placido de Titis’s Tabulae Primi Mobilis (1657) in 1789. However, the manuscript translation he published, which had been privately procured by a gentleman astrologer using a professional translator, did not include the extensive tables from the original Latin edition, to which Sibly lacked access. In 1790, he published his own set of tables together with the late John Partridge’s study of the nativity of Oliver Cromwell in a supplementary volume to the translation entitled ‘Supplement to Placidus de Titus’. This is reproduced in full here.
