1. Saint Eulalia. There are two Eulalia's: both Virgins. Which is intended?
1.1 One Eulalia from Merida, who at age 12 was martyred (tortured and burned) in December 304. Diocletian was Emperor of Rome at the time.
As to the burned Eulalia, the classical poet, Prudentius, in his poem Peristephanon, tells a different tale, but with similarities in the symbolism of doves. See Electronic Antiquity at http://scholar.lib.vt.edu/ejournals/ElAnt/V1N4/baker.html
The other Eulalia:
1.2 The second Eulalia from Barcelona, who was martyred earlier that same year, in February 304. She was exposed, unclothed in the town square, and the snow covered her, we are told. Then the angry Romans put her in a barrel, stuck knives in, and rolled her to death. She ultimately was made co-patron Saint of Barcelona. A bishop, however, once confused the issue and said they were one and the same.
In 1885, artist John William Waterhouse painted the martyred Barcelona girl (the one sprawled after her murder, not the burned one) but as a tantalizing woman, not a 12-year old. See http://www.aug.edu/augusta/iconography/eulaliaWaterhouse.html. That painting apparently has been a favorite of boys in the Tate gallery, London, since.
- Piety and little saints. Ensaint children who profess their faith and get killed by rulers for it. Then go on to kill others who profess their own faiths, differences from institutional authority, and call them heretics.
1.3 Fodor's Barcelona gives another narrative, ending with the crucifixion of Eulalia on an X-shaped cross.
1.4 The black Christ
Fodor's Barcelona also notes the black Santo Cristo de Lepanto, in a side chapel, see it at http://zeleste11.blogspot.com/2013/03/viernes-santo-2013-aquellas-salidas-que.html/. Do an images search.
The halo around this knight's head suggests sainthood. But who is it? He is upright, with his sword and full armor. Go back to Fodor's. If the knight is based on a wave-like support, could it be John of Austria, who commanded the Holy League's ships as a fleet; or is it a landlubber Lluis de Requesens, a Catalan aristocrat and general during the reign of Felipe II. Ask Fodor. I did an images search for Lluis there, and did not find this statue. Look up John of Austria: no, he is shown but not as a knight. However, he was a member of the Order of the Golden Fleece, and was victorious at Lepanto, and the black Christ is of Lepanto. See Wikipedia for John, 1547-1578, bastard son of Charles V at the roll call of members 1566, scroll around at http://en.wikipedia.org/wiki/List_of_Knights_of_the_Golden_Fleece#18th_Century
Is this another knight of the Golden Fleece, founded by Philip the Good, Duke of Burgundy in the early 15th Century, a multi-country chivalric order? More research needed. Meanwhile, read Rick Steves on this Cathedral at Rick Steves' Spain 2012. Including an unknown knight-saint here is for another purpose. See the size of the sword. From waist, and the handgrip(s), with the handle extending to rib cage, and the blade to the ground. That is the nature of sword-sizing. Get measured first.
