In 1723 Adam received the Melchior Cardinal de Polignac, and was purchased from his estate by Frederick the Great for Potsdam. For the ensemble Adam reworked draped torsos of ''Apollo Musagetes'' type for the figures of Odysseus and Achilles. The head of Achilles was modelled on the antiquarian Philipp von Stosch, "a notorious spy, homoerotic fop and gem collector" <ref>Seymour Howard, "Some Eighteenth-Century 'Restored' Boxers" ''Journal of the Warburg and Courtauld Institutes'' '''56''' (1993, pp. 238-255) p. 245. In the nineteenth century, after K. Levezow published the group (Levezow, ''Über die Familie des Lykomedes'' Berlin 1804),  the head of Stosch was lost, Howard relates (1993:245:note 35).</ref> Adam was elected a member of the Roman artists' guild, the Accademia di San Luca in 1732.<ref>His reception piece, a bust exprressive of ''Sorrow'', remains in the Accademia's collection.</ref> He was a ''pensionnaire'' of the Academy in 1732 when he was one of the sixteen sculptors and designers who submitted plans for the new Trevi Fountain; his design was unanimously accepted, and the process by which the decision was reversed in favour of Luigi Vanvitelli's are not altogether clear; Roman reaction against a foreigner receiving the commission seems to have played a part, and in a letter of 1741 Adam wrote that not having received prior permission to compete from the director of the Academy. Charles Wleughels, Adam was recalled home to Paris, in 1733, as punishment.<ref>A.

Adam was thirty-seven when, on his election to the Versailles, and it made his reputation;<ref>His brother Nicolas-Sébastien collaborated with him in the project.</ref> thereafter he found much employment in the decoration of the royal residences and in garden sculpture and fountains.

The dramatic realisation of his figure of ''Neptune'' (''illustration, left'') might lead one to expect that he would have been in demand for portrait busts; in fact, aside from the bust of the portrait-painter Hyacinthe Rigaud (1726), and two versions of the young Louis XV as Apollo,<ref>Terence Hodgkinson, "A Bust of Louis XV by Lambert Sigisbert Adam" ''The Burlington Magazine'' '''94''' No. 587 (February 1952), pp. 37-41, describes the terracotta bust (now in the Victoria and Albert Museum) that was exhibited in a plaster cast at the Salon of 1741 and the marble exhibited in 1745 and retouched and dated 1749, in the collection of Baron Maurice de Rothschild.</ref> none have been identified.

Among his more important works are:
*''The Virgin Appearing to St Andrew Corsini'' 1732, a relief for Pope Clement XII’s Cappella Corsini, San Giovanni in Laterano, Rome.  
* ''Nymphs and Tritons''
* ''Hunter with Lion in his Net'', a relief for the chapel of St Adelaide
* ''The Seine and the Marne'' (1733-34) in stone for Antoine Le Pautre's ''grand cascade'' at the Château de Saint-Cloud<ref>The group was reproduced for the Château de Pomponne, doubtless in the nineteenth century (Peter Fusco, reviewing Allan Braham and Peter Smith, ''François Mansart'' in ''The Art Bulletin'' '''58'''.2 (June 1976),p. 301.</ref>
* ''The Triumph of Neptune stilling the Waves'' 1737, reception piece for the Academy (Musée du Louvre).  
* ''Hunting'' and ''Fishing'', marble groups for Sanssouci
* ''Mars embraced by Love''
* ''The enthusiasm of Poetry''

The work of the brothers Adam was too boldly Berniniesque in style to win the approval of the sculptors and critics of the following generation, that found its principal protagonists in Edmé Bouchardon and Jean-Baptiste Pigalle. Pierre-Jean Mariette expressed the new taste in his severe criticism of the eldest of the Adam brothers:
:"''This artist put into everything that he did a savage and barbarous taste and only rendered himself noted because one imagined that no one knew how to carve out marble as he did, and, to demonstrate it, he worked in such manner that everything formed hollows in his works. Thus do his figures have more the air of rockwork than of anything else at all.''"<ref>''Cet artiste mettoit<!--mettoit, etc in original--> dans tout ce qu'il faisoit un gout sauvage et barbare et ne se faisoit regarder que parcequ'on imaginoit que personne ne scavoit fouiller le marbre comme lui, et, pour le persuader, il faisoit en sorte que tout formait trous dans son ouvrages. Aussi ses figures ont-elles plutost l'air de rochers que de tout autre chose.'' (Mariette's ''Abecedario'', quoted Hodgkinson 1952:40</ref>

'''Lambert Sigisbert Adam''', dit ''Adam l'aîné'', est un sculpteur français né à Nancy le 10 octobre 1700 et mort à Paris le 12 mai 1759.

==Biographie==
Fils du sculpteur François Dumont avant de passer dix ans à l'Académie de France à Rome, après avoir obtenu en 1723 le grand prix de sculpture. Durant son séjour, il fut protégé par le cardinal Melchior de Polignac, ambassadeur de France près le Saint-Siège, pour qui il restaura ou copia des statues antiques. C'est ainsi qu'il restaura habilement les douze statues trouvées dans la prétendue villa de Marius. Il fut également élu membre de l'Académie de Saint-Luc en 1732.

Durant ce très long séjour à Rome, il acquit une technique et une sensibilité qui le rattachent davantage au baroque qu'au rococo. En témoigne sa prédilection pour la mise en scène de l'eau, à travers des sculptures destinées à des fontaines ou des allégories. Il remporta en 1731 le concours pour la fontaine de Trevi à Rome, mais le pape Clément XII ne suivit pas le choix du jury et commissionna Nicola Salvi. 

Il travailla aux célèbres cascades du château de Saint-Cloud (''La Seine'' et ''La Marne''), sculpta le groupe central du bassin de Neptune du château de Versailles (''Triomphe de Neptune et d'Amphitrite'', 1740), travailla au palais de Sanssouci à Potsdam (''La Chasse'' et ''La Pêche''). ¨Pour sa réception à l'Académie royale de peinture et de sculpture en 1737, il donna un ''Neptune calmant les flots irrités''.
