I don't know of any Spanish translation of that book of Enriques you
quote, but a Spanish disciple of Enriques, Olegario Fernandez Ban~os
(1886-1946), coauthored with him a paper on non-euclidean geometries,
translated into our language as _Geometria no euclidea_ (Valladolid: Ed.
Lara, 1918, 48 pp.)
G.Israel ("Julio Rey Pastor e la matematica italiana: analisi di alcune
connessioni", in L.Espan~ol, ed., _Actas del I simposio sobre J.Rey Pastor_
[Logron~o: IER, 1985], pp.105-117) also provides this reference:
F.Enriques, "La evolucion del concepto de la geometria y la escuela
italiana durante los ultimos cincuenta an~os", _Revista Matematica
Hispano-Americana_, II (1920), pp.1-17.
