What Roman Goddess if wisdom and strategic warfare is featured on wood as a pignora imperii?
Minerva
Pignora imperii
The pignora imperii ("pledges of rule") were objects that were supposed to guarantee the continued "imperium" of Ancient Rome.
 One late source lists seven.
 The sacred tokens most commonly regarded as such were the Palladium, the wooden image of Minerva (Greek Athena) that the Romans claimed had been rescued from the fall of Troy and was in the keeping of the Vestals; the sacred fire of Vesta tended by the Vestals, which was never allowed to go out; and the "ancilia", the twelve shields of Mars wielded by his priests the Salii in their processions, dating to the time of Numa Pompilius, second king of Rome.
Minerva
Minerva ( ; ] ; Etruscan: "Menrva") was the Roman goddess of wisdom and strategic warfare, and the sponsor of arts, trade, and strategy.
 From the second century BC onward, the Romans equated her with the Greek goddess Athena.

Minerva 93 Berlin is a German association football club from the district of Moabit in the city of Berlin.
 The club was established 10 May 1893 as "Berliner Fußball Club Minerva" taking its name from the Roman goddess of wisdom.
 A merger with "Wilmersdorfer FC Frühling" in 1896 led to the club taking on the name "Sport-Club Minerva 93 Berlin". Proserpina
Proserpina ( ; Latin: "Prōserpina" ] ) or Proserpine ( ) is an ancient Roman goddess whose cult, myths and mysteries were based on those of Greek Persephone and her mother Demeter, the Greek goddess of grain and agriculture.
 The Romans identified Proserpina with their native fertility goddess Libera, daughter of the grain and agriculture goddess Ceres and wife to Liber.
 In 204 BC, a new "greek-style" cult to Ceres and Proserpina as "Mother and Maiden" was imported from southern Italy, along with Greek priestesses to serve it, and was installed in Ceres' Temple on Rome's Aventine Hill.
 The new cult and its priesthood were actively promoted by Rome's religious authorities as morally desirable for respectable Roman women, and may have partly subsumed the temple's older, native cult to Ceres, Liber and Libera; but the new rites seem to have functioned alongside the old, rather than replaced them. Duarte Pacheco Pereira
Duarte Pacheco Pereira (] ; c. 1460 – 1533), called the Portuguese Achilles ("Aquiles Lusitano") by the poet Camões, was a Portuguese sea captain, soldier, explorer and cartographer.
 He travelled particularly in the central Atlantic Ocean west of the Cape Verde islands, along the coast of West Africa and to India.
 His accomplishments in strategic warfare, exploration, mathematics and astronomy were of an exceptional level. Ancile
In ancient Rome, the ancilia (Latin, singular "ancile") were twelve sacred shields kept in the Temple of Mars.
 According to legend, one divine shield fell from heaven during the reign of Numa Pompilius, the second king of Rome.
 He ordered eleven copies made to confuse would-be thieves, since the original shield was regarded as one of the "pignora imperii", sacred guarantors that perpetuated Rome as a sovereign entity. Great Seal of California
The Great Seal of the State of California was adopted at the California state Constitutional Convention of 1849 and has undergone minor design changes since then, the last being the standardization of the seal in 1937.
 The seal features the Roman goddess Minerva (Athena in Greek mythology), the goddess of wisdom and war, because she was born an adult, and California was never a territory; a California grizzly bear (the official state animal) feeding on grape vines, representing California's wine production; a sheaf of grain, representing agriculture; a miner, representing the California Gold Rush and the mining industry; and sailing ships, representing the state's economic power.
 The word "Eureka" ("εύρηκα" in Greek), meaning "I have found it", is the California state motto. Athena
Athena ( ; Attic Greek: Ἀθηνᾶ , "Athēnā", or Ἀθηναία , "Athēnaia"; Epic: Ἀθηναίη , "Athēnaiē"; Doric: Ἀθάνα , "Athānā") or Athene ( ; Ionic: Ἀθήνη , "Athēnē"), often given the epithet Pallas ( ; Παλλὰς ), is the goddess of wisdom, craft, and war in ancient Greek religion and mythology.
