ROME: Italy's desire to court visiting Iranian President Hassan Rouhani extended to covering up classical nude sculptures in the museum where he met Prime Minister Matteo Renzi, it emerged on Tuesday.

The two men made speeches in Rome's Capitoline Museum after a Monday signing ceremony which saw Italian companies tie up $18 billion worth of deals with the Islamic Republic.

A huge statue of Roman emperor Marcus Aurelius on a horse featured prominently in many of the photographs of the event.

But nude statues, including a Venus dating from the second century B.C., had all been covered up in temporary wooden cartons, removing the risk of them creeping into any of the shots — or catching Rouhani's eye.

The museum cover-up was not the only step Italy took to ensure the Iranian visit passed off smoothly.

As Rouhani refuses to attend official meals at which any alcohol is available, wine was strictly off the menu at both lunch with President Sergio Mattarella and dinner with Renzi.

According to media reports, France has baulked at making a similar placatory gesture, leaving diplomats preparing for Rouhani's visit to Paris from Wednesday with a major protocol headache.
