           This Amendment No. 33 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, Hopa,
UCI and BCI are members of a group with respect to the Telecom Italia Shares.
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, Hopa, UCI or BCI has been provided by the
nominating person or by such nominee director or officer.

ITEM 2.    IDENTITY AND BACKGROUND

           On January 27, 2005, Olimpia announced that the Olimpia Capital
Raising (as that term is defined in Item 4 of Amendment No. 33 to the Statement
on Schedule 13D) had been fully subscribed. Each of Pirelli & C., Edizione
Finance and Hopa has subscribed for and purchased all of the Olimpia Shares that
were offered to it in connection with the Olimpia Capital Raising. In addition,
Pirelli & C. has subscribed for and purchased all of the Olimpia Shares that
were offered to each of BCI and UCI in connection with the Olimpia Capital
Raising. After giving effect to the issuance of Olimpia Shares to each of
Pirelli & C., Edizione Finance and Hopa, the share capital of Olimpia is held by
Pirelli & C., Edizione Finance, Hopa, BCI and UCI in the following respective
proportions: 57.66%, 16.8%, 16%, 4.77% and 4.77%. A copy of a press release
issued by Olimpia on January 27, 2005 concerning the Olimpia Capital Increase is
filed as Exhibit 76.

ITEM 3.    SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION

           Reference is made to the Mediobanca Forward Sale Agreement, the
Caboto Forward Sale Agreement and the JPMorgan Forward Sale Agreement (as each
of those terms is defined in Item 4 of Amendment No. 33 to the Statement on
Schedule 13D). On February 16, 2005, Olimpia announced that it had purchased:
(i) 135,291,206 Telecom Italia Shares from Mediobanca at a price per share of
3.0305 euro pursuant to the Mediobanca Forward Sale Agreement; (ii) 130,300,000
Telecom Italia Shares from Caboto at a price per share of 3.0549 euro pursuant
to the Caboto Forward Sale Agreement; and (iii) 424,130,480 convertible bonds
issued by Telecom Italia (which are convertible into an aggregate of 200,000,000
Telecom Italia Shares) from JPMorgan at a price per share (on an as converted
basis) of 3.1299 euro pursuant to the JPMorgan Forward Sale Agreement. In each
case, Olimpia obtained the purchase price from capital contributed by its


                               Page 4 of 8 pages

shareholders in connection with the Olimpia Capital Raising. A press release
issued by Olimpia on February 16, 2005 concerning the transactions (and which
announces that Olimpia will soon convert the convertible bonds into Telecom
Italia Shares) is filed as Exhibit 77.

ITEM 4.    PURPOSE OF TRANSACTION

           On February 16, 2005, Olimpia entered into a forward sale agreement
with Mediobanca (the "February 2005 Mediobanca Forward Sale Agreement") pursuant
to which Olimpia agrees to purchase from Mediobanca certain Telecom Italia
Shares for an aggregate purchase price of 283,000,000 euro. The purchase price
per Telecom Italia Share will be determined by reference to the price paid by
Mediobanca to acquire such Telecom Italia Shares during the term of the February
2005 Mediobanca Forward Sale Agreement (subject to minor adjustments to reflect
transaction costs that may be incurred by Mediobanca), but will not in any event
exceed 3.50 euro. The number of Telecom Italia Shares to be acquired by Olimpia
pursuant to the February 2005 Mediobanca Forward Sale Agreement will be
determined by dividing 283,000,000 euro by the price per Telecom Italia Share
determined in accordance with the previous sentence. If the weighted average
market price of Telecom Italia Shares exceeds 3.50 euros for any seven
consecutive trading days during the term of the February 2005 Mediobanca Forward
Sale Agreement, then either party may convene a meeting with the other party for
the purpose of renegotiating the terms of the purchase and sale of the Telecom
Italia Shares. If the parties are unable to reach an agreement within five
trading days following the date of such meeting, then Mediobanca will be
required to sell to Olimpia only that number of Telecom Italia Shares as
Mediobanca has acquired by such date in contemplation of its obligations under
the February 2005 Mediobanca Forward Sale Agreement. Settlement of the
transactions contemplated by the Mediobanca Forward Sale Agreement will occur on
a date (which is to be determined by Olimpia) between February 28, 2005 and May
31, 2005. A copy of an English translation of the February 2005 Mediobanca
Forward Sale Agreement is filed as Exhibit 78.

           Also on February 16, 2005, Olimpia entered into a forward sale
agreement with Caboto (the "February 2005 Caboto Forward Sale Agreement")
pursuant to which Olimpia agrees to purchase from Caboto certain Telecom Italia
Shares for an aggregate purchase price of 283,000,000 euro. The material terms
of the February 2005 Caboto Forward Sale Agreement are identical to those of the
February 2005 Mediobanca Forward Sale Agreement described in the preceding
paragraph. A copy of an English translation of the February 2005 Caboto Forward
Sale Agreement is filed as Exhibit 79.
