Book review of Ana María Mora-Márquez, 'The thirteenth-century notion of signification : the discussions and their origin and development.' (Investigating medieval philosophy 10.) Leiden and Boston : Brill, 2015. Pp. 256. $142. ISBN : 978-900-429867-5.

In this slim, dense, and heavily text-based book, Mora-Márquez traces the development of the semantic notion of ‘signification’ (significatio) from its origins in two distinct Greek philosophical conceptions, semeion and symbolon, into a uniquely medieval concept. Because medieval philosophers drew from both logical and grammatical traditions when discussing signification, there is no unified conception of the notion which holds across the entire 13th century or in all relevant disciplines. Mora-Márquez teases out the differences, explains how they relate to each other, and identifies the roots of the differences. Due to the complexity of the material, the book requires careful thought and attention in order to grasp all of the subtle nuances in the ancient and medieval views
