The cyclogram method of time series analysis has been used to analyse 10Be data (1181–1800 AD) and δ18O data (1181–1960 AD) from an artic ice core and thermoluminescence data (1181–1960 AD) from a Mediterranean sediment core. The10Be concentrations were determined at the ETH Zurich. The δ18O values were measured at the University of Copenhagen. The TL measurements were performed at the Istituto di Cosmo-geofisica del C.N.R., Torino. Common mean periodicities of 10.75 y are found for the period 1505 to 1710 AD in TL and10Be and of 11.4 y for the period 1715 to 1880 in TL and δ18O. This periodicity was found in the solar sunspot (R z) series analysed in the same way, from 1825 to 1905. This supports the argument that the common periodicities found in the long-running series are peculiar of the solar activity in the past.
