                 This Amendment No. 47 amends the Statement on Schedule 13D,
dated August 9, 2001, as amended (as previously amended, the "Statement on
Schedule 13D"), filed by Pirelli S.p.A. (which, as reported in Amendment No. 21
to the Statement on Schedule 13D, subsequently merged with and into Pirelli & C.
S.p.A., a company incorporated under the laws of the Republic of Italy), and,
commencing with Amendment No. 1 thereto, Olimpia S.p.A., a company incorporated
under the laws of the Republic of Italy, 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.

                  Pirelli & C., Olimpia, Edizione Holding and Edizione Finance
are members of a group with respect to the Telecom Italia Shares. (By virtue of
the 2006 Shareholders Agreement described in Amendment No. 45 to the Statement
on Schedule 13D, Assicurazioni Generali S.p.A. and Mediobanca S.p.A. may also be
deemed to be members of that group.) This Amendment constitutes a separate
filing on Schedule 13D by Pirelli & C. and Olimpia in accordance with Rule
13d-1(k)(2) under the Securities Exchange Act of 1934. Pirelli & C. and Olimpia
are responsible solely for the information contained in their separate filing,
except that information contained in the Statement on Schedule 13D concerning
any director or officer of Olimpia nominated by Edizione Holding or Edizione
Finance has been provided by the nominating person or by such nominee director
or officer.

ITEM 2.  IDENTITY AND BACKGROUND

         On December 19, 2006, a shareholders' meeting of Olimpia resolved to
amend the by-laws of Olimpia by (a) reducing the size of the board of directors
from ten to six (and limiting the number of directors that may be drawn from any
individual shareholder's list of nominees to half of the total number of
directors) and (b) reducing to 81 percent the proportion of the total number of
Olimpia shares required to be (i) represented at an extraordinary shareholders
meeting in order to constitute a quorum and (ii) affirmatively voted in order to
approve any resolution at an extraordinary shareholders meeting.

         Also at the shareholders' meeting of Olimpia, each of the following
individuals was elected to the board of directors for a term of three fiscal
years: Mr. Marco Tronchetti Provera, Mr. Carlo A. Puri Negri, Mr. Luciano Gobbi,
Mr. Gilberto Benetton, Mr. Gianni Mion and Mr. Giancarlo Olgiati. Each of
Messrs. Tronchetti Provera, Puri Negri and Gobbi was nominated by Pirelli & C.,
and each of Messrs. Benetton, Mion and Olgiati was nominated by Edizione Holding
and Edizione Finance. (Subsequently, at a meeting of the Olimpia's board of
directors held on the same date, Mr. Tronchetti Provera was confirmed as
Chairman of Olimpia and Mr. Benetton was confirmed as Vice-Chairman of Olimpia.)
Information concerning each of Messrs. Tronchetti Provera, Puri Negri, Gobbi,
Benetton and Mion has previously been filed on this Statement on Schedule 13D.
Mr. Olgiati's present principal occupation is partner of the Swiss law firm of
Ghiringhelli, Olgiati e Asssociati and his business address is Via Nassa 38,
6900 Lugano, Switzerland. Mr. Olgiati is a Swiss citizen. He does not
beneficially own any securities of Telecom Italia.


                               Page 4 of 7 pages

         During the past five years, to the knowledge of Pirelli & C. and
Olimpia, Mr. Olgiati has not been (i) convicted in any criminal proceeding
(excluding traffic violations or similar misdemeanors) or (ii) a party to a
civil proceeding of a judicial or administrative body of competent jurisdiction
as a result of which he was or is subject to a judgment, decree or final order
enjoining future violations of, or prohibiting or mandating activity subject to,
federal or state securities laws or finding any violation with respect to such
laws.

         A copy of a press release issued by Olimpia in connection with the
December 19, 2006 shareholders' meeting is filed as Exhibit 107.

ITEM 5.  INTEREST IN SECURITIES OF THE ISSUER

         Reference is made to the swap transaction between Pirelli & C. and
Credit Agricole Lazard Financial Products Bank ("Calyon") described in Item 5 of
Amendment No. 7 to the Statement on Schedule 13D (the "Calyon Swap
Transaction"). On November 23, 2006, the parties settled the Calyon Swap
Transaction in cash without the physical delivery of any securities.

         Reference is made to the equity swap transaction between PFL and
JPMorgan Chase Bank ("JPMorgan") described in Item 5 of Amendment No. 10 to the
Statement on Schedule 13D (the "JPMorgan Swap Transaction"). On December 19,
2006, the parties settled the JPMorgan Swap Transaction in cash without the
physical delivery of any securities.
