	<abstract content_type="html">Paintings created by famous artists, representing sunsets throughout the
period 1500&amp;ndash;1900, provide proxy information on the aerosol optical depth
following major volcanic eruptions. This is supported by a statistically
significant correlation coefficient (0.8) between the measured red-to-green
ratios of 327 paintings and the corresponding values of the dust veil index. A radiative
transfer model was used to compile an independent time series of aerosol
optical depth at 550 nm corresponding to Northern Hemisphere middle latitudes
during the period 1500&amp;ndash;1900. The estimated aerosol optical depths range from
0.05 for background aerosol conditions, to about 0.6 following the Tambora
and Krakatau eruptions and cover a time period mostly outside of the
instrumentation era.</abstract>
