Deneb Algedi

Deneb Algedi is one of the stars directly preserved in the local Behenian corpus. That makes its traditional operation much clearer than the old draft allowed. The local materials do not point to a vague all-purpose success star. They point to a narrower cluster of household, legal, and prosperity uses. (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 Deneb Algedi with chalcedony and marjoram, with Agrippa also adding mugwort, catnip, and mandrake root. The operation preserved in the Bodleian line is unusually practical: favor in lawsuits, improvement and security of the home, and increase of riches. Agrippa keeps the prosperity emphasis even where his image tradition differs in tone. (Warnock, Fixed Star, Sign and Constellation Magic; Agrippa, Three Books, Book I and Book II, ch. 47)

Brady's concise modern keyword for Deneb Algedi is law giving, which is a useful fit for the lawsuit and order-making logic already present in the local magical material. That later shorthand works best when it stays tied to the older corpus rather than replacing it. (Brady, Brady's Book of Fixed Stars)

So the reliable summary is straightforward: Deneb Algedi is a Behenian star for ordered increase, household security, and legal advantage when used in a disciplined stellar framework.
