Artistic temperament

We've all heard about how artists of all kinds can be very emotional and temperamental. It probably isn't true of many artists, but by all accounts, it was true of Juan Luna (October 23, 1857 – December 7, 1899), the painter of yesterday's Spoliarium. Born in the town of Badoc in the province of Ilocos Norte, Luna was discharged from one art school in Manila because he refused to follow what his teacher wanted, and he left another in Madrid because he didn't like their teaching style. He married Maria de la Paz Pardo de Tavera in 1886 and they settled in Paris. Only six years later, Luna, in a fit of jealousy, killed his wife and mother-in-law, and wounded his brother-in-law. This small sketch of Juan Luna hangs in the Luna and Hidalgo Gallery of the National Art Gallery, where the Spoliarium is also located. I now forget if this was a self-portrait or drawn by an artist friend. It was done in Rome in 1879, before the Spoliarium and before the marriage, and he does not yet have the handlebar mustache of his later portraits and photos.
