Arcturus is one of the directly attested Behenian stars in the local corpus. That classical status is more important for this page than any later generalized fixed-star language. The local magical texts give Arcturus a compact but clear operation built around bodily protection rather than an abstract success mythology. (Hess and Warnock, De Quindecim Stellis; Agrippa, Three Books, Book II, ch. 47)

Warnock's summary of the Bodleian material and Agrippa's list pair Arcturus with jasper and plantain. The Bodleian line is especially concrete: fever relief and restraint of blood. Agrippa keeps the same direction when he says the Arcturus image is good against fevers and astringes the blood. That gives the page a historically grounded center of gravity. (Warnock, Fixed Star, Sign and Constellation Magic; Agrippa, Three Books, Book I and Book II, ch. 47)

Ptolemy gives Arcturus a Jupiter-and-Mars nature, and Brady's modern keyword for it is pathfinder. Those later interpretive layers are useful because they describe the star's outward style without replacing its older medical-protective operation. (Ptolemy, Tetrabiblos, Book I, ch. 9; Brady, Brady's Book of Fixed Stars)

For this section, the cleanest summary is that Arcturus is a Behenian star of directed help: a star used in the local corpus for fever work, blood restraint, and firm, practical guidance.
