_ (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.

‘Incipit liber 4 tractatuum Ptolomei Alfilludhi in scientia iudiciorum astrorum. Et in primo tractatu sunt 24 capitula. Capitulum primum in collectione intellectus scientie iudiciorum astrorum.

Explicit liber 4 Tholomei in iudicandi discretione per stellas de futuris et in hoc mundo constitutionis et destructionis contingentibus.’

. I, 41ra-63ra; II, 63ra-83ra; III, 83ra-112va; IV, 112va-128va. Substantial glosses by the scribe, which often open ‘Sensus huius littere est…’, ‘In alio...’ or ‘Dicit Haly…’. On f. 96r the size of the main text has been reduced so as to leave more room for the glosses, which shows that the text and the glosses were meant to form one unit. Occasional glosses by a later hand.
