Mars and Mercury, and a Mixed Reputation

The tradition gives Bellatrix the nature of Mars with Mercury, Ptolemy reads the bright stars in Orion's shoulders in that martial-mercurial register, and Robson delineates it for sudden success followed by trouble, with an old and unflattering reputation for those born under it, especially in the misogynistic key of some medieval sources. That last layer is worth naming as period prejudice rather than passing it on as fact. The dependable statement is the simpler one: Bellatrix is a hot, luminous, blue star of Orion, and the elaborate character readings attached to it are late and contradictory.

The "Amazon Star" label and its unusually gendered martial reading sit oddly against Ptolemy's own comparatively restrained treatment of Orion's shoulder stars in the Tetrabiblos, which gives the region a Mars-and-Mercury nature without the elaborate misogynistic gloss later medieval commentators layered onto it; separating what Ptolemy actually wrote from what later centuries added to his bare attribution is one of the more consistently useful exercises across this whole catalogue. The martial-mercurial pairing given to Bellatrix is shared with several other stars in Orion's frame, part of a broader classical reading of the whole constellation as a warlike figure, hunter and weapon together, that colours every bright star within its outline.
