This volume provides the first full study of Thomas Gallus (d. 1246) in English and represents a significant advance in his distinctive theology. Analytically, Coolman's assessment of Gallus is clear, well written, and engaging, though highly technical, and would likely be a resource for graduate students and professors of theology and philosophy... In sum, this book is highly recommended for both historical and systematic theologians, as well as those interested in medieval Neoplatonic philosophy.
