            This Amendment No. 53 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, Sintonia S.p.A. (which, it publicly announced
on March 9, 2007, has replaced Edizione Holding in various shareholders
agreements relating to Olimpia) and Sintonia S.A. (which, according to Sintonia
S.p.A.'s public announcement, is the new name of 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 Sintonia S.p.A., its predecessor
Edizione Holding or Sintonia S.A. has been provided by the nominating person or
by such nominee director or officer.

ITEM 4.  PURPOSE OF TRANSACTION

            On April 16, 2007, Pirelli & C. issued a press release which
reported the decision of AT&T Inc. to withdraw its offer for the acquisition of
a participation equal to one-third of the share capital of Olimpia and America
Movil's intention, in conjunction with Telefonos de Mexico S.A.B. de C.V., to
continue considering different alternatives for a potential investment in
Olimpia. A copy of the press release is attached as Exhibit 113.
