4 vols. 32mo. (75 x 47mm), pp. [ii], 158; 186, [iv]; 128; 79, [I] + the rest of the text block made up with a roughly equal number of binder’s blank leaves. Title-page to each volume, additional series title to volume I. Vol. I without its final blank, vol. II with both final blanks. First words of title transliterated from Greek. Occasional spotting and light toning, a few faint stains, very good. Early c.20th dark blue crushed Morocco, gilt titles to spines, top edges gilt, ornate gilt dentelles. Spines a little sunned, lightly rubbed, very good indeed.
