For instance, the author that is commentating on the primary source is named Foster.
The primary source is Dante's Inferno. I want to make reference to the primary source that Foster is addressing in the in-text citation but I also want to reference Foster.
In APA format, should the sentence look like this:
Foster (1964) notes that Dante makes use of x, y and z (p. 101, Inf. XVI, 23).
p. 101 is for Foster, while Inf. XVI, 23 is for Dante.
