AB We present new archaeointensity results from three Italian kilns situated at Ascoli Satriano,Vagnari and Fontanetto Po obtained with the Thellier modified by Coe double heating method.These data complement the directional results previously published. All sites are dated onthe basis of archaeological information and/or thermoluminescence dating. The results arecorrected for the anisotropy of the thermoremanent magnetization and the cooling rate effects.The new data are compared with previously published archaeointensity data from Italy andnearby countries within 900 km radius from Viterbo. An initial data set including archaeointesitydata mainly coming from Italy, France, Switzerland, Czech Republic, Slovakia, Hungary,Greece and Bulgaria has been compiled. After the application of strict selection criteria, themost reliable data have been used for the calculation of a preliminary Italian intensity secularvariation (SV) curve for the last 3000 yr. The new curve covers the 300 BC–400 ADand 1200–1900 AD periods. It is established by means of sliding windows of 200 yr shiftedby 100 yr. The lack of reliable data for the 1000–200 BC and 400–1200 AD time intervalsdoes not permit the calculation of a continuous curve. Clearly, more high-quality archaeointensitydata from Italy and Europe are still needed to draw a robust intensity SV curve forthe Italian Peninsula that could be used for archaeomagnetic dating in combination with the directional data.
