LONDON -- Old Master drawings owned by the duke of Devonshire brought 6.29 million pounds -- about $10 million -- at auction last night. Record prices were paid for works by Barocci, Rembrandt and Veronese.

It was the duke's third sale in recent years. He will use the proceeds for long-term preservation of Chatsworth House in Derbyshire, northern England, and the mansion's art collection, which includes nearly 2,000 drawings.

David Tunick, a New York dealer, paid $2.8 million for the 1576 drawing "Madonna del Popolo" by Italian master Federico Barocci, the highest price at the Christie's auction.

A drawing by Rembrandt brought the second-highest price, $2.2 million, also a record for the artist. "The Ramparts Near the Bulwark Beside the St. Anthoniespoort" went to London dealers Baskett and Day.

Next came a record $974,050 for a drawing by Paolo Veronese, "The Martyrdom of Saint Justina," sold to a buyer whose name was not revealed.

An anonymous buyer paid $885,500 for "The Death of Saint Peter Martyr" by Giovanni Antonio da Pordenone.

Also included in the 16 drawings offered for sale were works by Raphael, Sir Anthony van Dyke and Antonio Correggio.

The sale had been expected to bring $8 million, but surpassed the estimate even though four drawings were withdrawn because they did not meet the reserve prices.

Lord Hartington, the duke's heir, said all the works had been offered to the British Museum and other British institutions, which turned them down.

In July 1984, an auction of 70 drawings from Chatsworth brought $28 million, which at the time was the highest total achieved at a single auction. The duke had offered those drawings for $9.1 million to the British Museum.

A sale of 176 Old Master prints from Chatsworth in December 1985 broke more records. Last night Christie's also sold 11 previously unpublished drawings by Peter Paul Rubens for $1.9 million.
