Saturn and Venus, an Unlucky Reputation

Ptolemy gives the star in the lion's tail the nature of Saturn with Venus, and the later tradition turned this into one of the more ill-omened delineations in the catalogue: Robson reads Denebola for misfortune, disgrace, regret and reversal, and older Arabic material associated the region with sudden calamity. The chain from a bare Ptolemaic pairing to a full sentence of doom is the standard pattern with this material, and the doom is mostly late. The star itself is unremarkable in reputation's sense and remarkable in fact, a nearby, young, dusty A-type star of exactly the kind now searched for planets.

That Denebola's harsh reputation is "mostly late" can be checked directly against Ptolemy's own wording, which assigns Leo's stars a Saturn-and-Venus nature in general terms without singling out the tail star for any of the specific disasters, disgrace, or reversal that the Victorian compilers later attached to it by name. Robson's specific wording for Denebola draws heavily on earlier nineteenth-century compilations by authors such as Ebertin and the older Arabic-derived lists translated into English during the same period, part of the same broad chain of transmission visible throughout this catalogue.
