_ (the underscore) is the placeholder for exactly one character.
% (the percent sign) is the placeholder for no, one or more than one character.
%% (two percent signs) is the placeholder for no, one or more than one character, but not for blank space (so that a search ends at word boundaries).

At the beginning and at the end, these placeholders are superfluous.

Work B.1.1

Centiloquium (tr. Adelard of Bath)


‘(ed. Lemay/Boudet) [1] Doctrina stellarum ex te et illis. Nec est docti in ea ut propherret formam actus individualis… [2] Cum quesierit electionem meliorem, non est inter eum… [3] Connaturalis in re est cui invenitur dux huius rei… [4] Anima connaturalis iudicabit super elthenias, id est secundas stellarum… [5] Iam potest astrologus super removendos multos actus stellarum… [6] Proderit autem cum electione cum fuerit bona… [7] Non accedat ad iudicium supra complexiones stellarum… [8] Anima sapiens actus stellarum adiuvat sicut seminator… [9] Forme que in mundo composito sunt formis circularibus… [10] Subserviant tibi infelicitates in electionibus… [39] Mala habitudo undecimi et domini eius in statutione — supra parvitatem lucri agricolarum suorum cum eo.’


Translated from Arabic by Adelard of Bath, probably around 1120. The text does not include the Arabic commentary and breaks off after v. 39 in all manuscripts. Besides the two manuscripts noted below, this version also occurs in the so-called ‘threefold version’ (see under Plato of Tivoli, B.1.2).
