What mysteries lie behind Salamanca university¡¯s famous facade?

One of the biggest challenges for both visitors and students is to spot the famous frog among this forest of faces ¨C the highbrow equivalent to Where¡¯s Wally? Failure to pinpoint the elusive creature traditionally meant that medical students would fail to graduate.

The facade is possibly the best example there is of Plateresque (or silversmith-like) architecture peculiar to Spain and its territories during the early Renaissance period, and the university¡¯s upcoming 800th anniversary in 2018 has prompted a restoration project that will be completed by the end of November after four months of demanding work.

Among the surprising findings is the existence of two pieces of 18th-century graffiti

Architect Jes¨²s Castillo Oli, director of the Santa Mar¨ªa Foundation Heritage Conservation department and the figure responsible for the restoration, explains that although the facade was in decent shape, the elements have taken an inevitable toll on the sculptures and more than 50 people have been involved in restoring them, using funds donated by the regional government of Castile and Leon (€220,000), the University itself (€220,000) and Salamanca-based energy company, Enusa (€125,000).

Castillo points out that the intricacy of the sculptures complicates the job of eliminating blemishes such as the black stains that have appeared on the pink stone. In order to avoid further deterioration, the cleanup process calls for the gentlest of techniques. ¡°Afterwards, if the sillar stone is crumbling, it is strengthened and toned to bring out the color,¡± he explains.

One of the most surprising findings since the restoration work began late summer is the inscription ¡°Espedici¨®n 1853¡±. That year a teacher and his students from the recently created Madrid Architecture School clambered up scaffolding and one graffiti artist left his trace ¨C twice.

Several meters below, Castillo touches the lichen that puts down roots in the stone, then he mentions the damaging acidity of pigeon waste. Up close, the damage is all too obvious. ¡°Considering how extraordinary the sculptures are, there are aspects at the top that have been poorly structured architecturally speaking ¨C stones that are out of line,¡± says Castillo. ¡°You can see that when they were brought from the workshop, they didn¡¯t fit the space allowed for them.¡±

The sketchy alignment isn¡¯t the only puzzle surrounding the facade. Salamanca lecturer, Eduardo Azofra, is familiar with the enigmas attached to this triumph of horror vacui ¨C the practice of filling the entire surface of an artwork with detail. ¡°We don¡¯t know the exact date of its construction because all the university archives from this period have been lost,¡± he says. ¡°But the facade doesn¡¯t date back to before 1512 and it was probably finished by 1529. In one document dated 1528, architect Juan de ?lava speaks about the library that lies behind what was called ¡°la portada rica¡± ¨C or the ornate entrance.

Azofra says the biggest question is who was responsible for the building of a facade with so many cultural references, clearly designed for a highly learned audience. Several historical characters have been mooted, such as Joanna of Castile, the Mad. ¡°There¡¯s a book from 1666 in the University that states she paid for the facade, though it¡¯s the only document to do so,¡± he says.

Another massive question mark hangs over who actually carried out the work. During the period in question, there were a number of prestigious architects in Salamanca due to the construction of the new cathedral. But historian Alicia M. Canto points to the existence of the initials I.T.A. on the?facade as evidence that the architect Juan Talavera was behind the project.

No other building in the city bears these initials but Talavera was closely linked to Joanna the Mad.

Whoever was behind the project, they factored in a 30cm tilt from the base to the top to give a better view of the whole facade from the ground. And besides the main architect, there would, as Azofra suggests, have been various sculptors involved.¡°The style of each of the three horizontal bodies is completely different,¡± he says.

The quality of the uppermost body led historian Mart¨ªn Gonz¨¢lez to suggest the sculptor was Alonso Berruguete. Meanwhile, a certain uniformity prevails in some of the panels that were inspired by Italian engravings.

Interpreting the sculpted figures is a complex business. Theories from historians during the 1970s suggested that the facade was divided, like a renaissance palace, into two halves with one half representing virtue and the other, vice. However, French historian Paulette Gabaudan believes it was built as a tribute during the reign of Charles V. Art history expert, Felipe Pereda took this idea further, suggesting it was actually a tool for the instruction of Charles V, with historical and mythological references which would be key to both his education and his successful rule.

Looking for the famous frog on the facade is a highbrow version of ¡®Where¡¯s Wally?¡¯

The latest theory maintains that the facade represented the idea that Charles, as the emperor of the Holy Roman Empire had been called to follow the four great empires of the earth, namely Babylon, Greece, Carthage and Rome. ¡°There was both political and religious intent in the fashioning of the facade,¡± says Azofra. ¡°The university is indebted to both the monarchy and the papacy.¡±

But what about the frog? A tourist attraction, the source of legend and perhaps a warning against lust, the frog upset local novelist Miguel de Unamuno, who is thought to have said: ¡°It¡¯s not that they see vice in the frog, it¡¯s just that the frog is all they see.¡± This is substantiated by a scratch on a photo of the facade prior to its restoration at the university entrance, marking the location of the famous amphibian.
