Meaning
Point, sharpness
Lewis and Short's A Latin Dictionary (1879), under acumen, gives the Latin meaning recorded here. Robson uses the name for M7 in the Scorpion's sting (1923, printed page 117). Allen discusses M6 and M7 together in the Scorpio chapter and quotes the Latin aculeum for the sting (1899, printed page 370).
Acumen in Astrology
Repeated criticism can wear down the resolve to answer it. Brady reads Acumen through that pressure and names Vincent van Gogh and Marilyn Monroe among her examples. Robson's 1923 entry gives Acumen the same blindness prediction as Aculeus, while Brady's summary of Rigor adds eyesight problems and illness. Those claims belong to the old predictive register and need weighing against the whole chart. Brady's practical counsel is to address the problem openly before resentment starts directing the response.
Mythology & History
Brady treats Acumen and Aculeus together through the Scorpion's sting and the pair's Fish Hook name. Her Acumen reading emphasizes the wearing effect of opposition. She supplies no separate myth for Acumen (printed pages 288 to 291).
Robson's 1923 entry 5 calls Acumen a companion cluster with the same nature and influence as Aculeus, including its Mars and Moon nature and its eyesight warning (printed page 117). Brady's account of Rigor adds illness and extreme disfavor to Acumen's old predictive register, then develops her own reading of the wearing effect of opposition (printed pages 288 to 291). Brady gives natal and paran readings only; the crossing reading here applies her account of the star.
Scorpius Context
Robson identifies Acumen as M7 Scorpii beside Aculeus above the sting (1923, printed page 117). Allen names M7 as NGC 6475 and places it with M6 along an extension of the sting (1899, Scorpio chapter, printed page 370). Brady identifies M7 Scorpius in paran map 54 (printed page 290). This catalog row represents the cluster centre, so it has no single stellar spectral type.

Notable Charts
Charlie Chaplin
Acumen setting as the Moon sets, in permanent curtailed passage
Brady lists the paran in Chaplin's full star report and reads its curtailed passage through his being forced to leave the United States despite his innocence, in her account (printed pages 354 to 356, with the departure discussion on page 356).
Jacqueline Kennedy
Aculeus and Acumen setting as Mercury reaches the Nadir
Brady's 1963 solar return gives both clusters this paran, with passage. She assigns the setting stars to March through July 1964 and reads the pair with Mercury through the nation's grief after the assassination of John F. Kennedy (printed pages 363 to 365, with the paired-star discussion on page 364).
