         This Amendment No. 17 amends the Statement on Schedule 13D dated August
9, 2001, as amended (as previously amended, the "Statement on Schedule 13D")
filed by Edizione Holding S.p.A., a company incorporated under the laws of the
Republic of Italy ("Edizione Holding"), Edizione Finance International S.A., a
company incorporated in the Duchy of Luxembourg ("Edizione Finance"), and
Ragione S.a.p.a. di Gilberto Benetton e C., a partnership organized under the
laws of the Republic of Italy ("Ragione") (Edizione Holding, Edizione Finance
and Ragione, are collectively referred to herein as the "Edizione Reporting
Persons") with respect to the ordinary shares, euro 0.55 par value per share, of
Telecom Italia S.p.A., a company incorporated under the laws of the Republic of
Italy. Capitalized terms used in this Amendment without definition have the
meanings ascribed to them in the Statement on Schedule 13D.

         This Amendment is being filed by each of the Edizione Reporting
Persons. Pirelli, the Purchaser, Edizione Holding, UCI, BCI, and, as discussed
in Items 4 and 6 of Amendment No. 10 to the Statement on Schedule 13D, Hopa are
members of a group with respect to the Telecom Italia Shares. The Edizione
Reporting Persons are making a separate filing on Schedule 13D in accordance
with Rule 13d-1(k)(2) under the Securities Exchange Act of 1934 and are
responsible solely for the information contained in this filing, except that
information contained in the Statement on Schedule 13D concerning any director
or officer of the Purchaser nominated by Pirelli, UCI, BCI or Hopa has been
provided by the nominating person, and the information concerning Mr. Emilio
Gnutti has been provided directly by Mr. Gnutti.

Item 3.  Source and Amount of Funds or Other Consideration

         On October 15, 2003, Olimpia purchased 266,300,000 Telecom Italia
Shares for an aggregate purchase price of approximately euro 597.7 million,
representing the price per share of euro 2.2445. The transaction occurred in
connection with the simultaneous sale by Olimpia of its entire holding of
504,825,562 Telecom Italia 2001-2010 convertible bonds for a price per
convertible bond of 1.172 euro plus accrued interest, and involves a nominal
cash settlement of approximately euro 3,000 to be received by Olimpia. A copy of
a press release concerning the transaction issued by Olimpia on October 15, 2003
is filed as Exhibit 41. Approximately 492 million of the Telecom Italia
2001-2010 convertible bonds that were sold by Olimpia on October 15 had been
(until the time of their sale) pledged with Banca Intesa, Banca di Roma,
Unicredit Banca Mobiliare S.p.A. and Unicredit Banca D'Impresa S.p.A. pursuant
to the Pledge Agreement filed as Exhibit 19 to the Statement on Schedule 13D. In
substitution for those bonds, 259,797,136 of the Telecom Italia Shares that were
purchased by Olimpia on October 15 have been pledged pursuant to the Pledge
Agreement.

Item 5.  Interest in Securities of the Issuer

                  After giving effect to the acquisition of the 266,300,000
Telecom Italia Shares referred to in Item 3, Olimpia holds 1,457,015,823 Telecom
Italia Shares, representing approximately 14.16% of the total number of
outstanding Telecom Italia Shares.
