[61] A small collection, formed by Don Emilio Rotondo, of primitive iron rings, bracelets, brooches, and other ornaments, is preserved in the Schools of Aguirre at Madrid. Villa-amil y Castro (_Antigüedades prehistóricas y célticas_, and _Castros y Mamoas de Galicia_, published in the _Museo Español de Antigüedades_), describes some iron objects of uncertain use discovered in Galicia, together with spear-heads and other weapons or pieces of weapons which will be noticed under _Arms_, and also an object which he says may once have been a candlestick, or else a kind of flute. All these are probably pre-Roman. Dating from the Roman period are an iron ploughshare and some sickles, discovered at Ronda in Andalusia, and now in the Madrid Museum. Góngora, however (_Antigüedades prehistóricas de Andalucía_), inclines to think that previous to the Roman conquest the occupants of Betica were ignorant of this metal, though not of gold, from which they fashioned diadems and other articles of wear. See also Caballero Infante, _Aureos y barras de oro y plata encontrados en el pueblo de Santiponce_, Seville, 1898. The decorative iron-work of Spain may suitably be dealt with in three classes: railings, screens, or pulpits of churches, chapels, and cathedrals; balconies and other parts or fittings applied to public or private buildings of a non-ecclesiastical character; and smaller, though not necessarily less attractive or important objects, such as knockers, locks and keys, and nail-heads. The last of these divisions, as embracing Spanish-Moorish craftsmanship, shall have, as far as order is concerned, our preferential notice.
