Abstract. A new technique is described for explicitly evaluating quotients of the Dedekind eta function at quadratic integers. These evaluations do not make use of complex approximations but are found by an entirely ‘algebraic’ method. They are obtained by means of specialising certain modular equations related to Weber’s modular equations of ‘irrational type’. The technique works for a large class of eta quotients evaluated at points in an imaginary quadratic field with discriminant d ≡ 1 (mod 8). In particular, this method does place any restriction on the class number of the associated imaginary quadratic number field
